How to find y-intercept with two points.
To find where y=1/2x+5 and the original line y=-2x intersect, set them equal to each other. Let y in both of the equations equal the same value. You are doing this because at the two lines' point of intersection, both lines will share the same x and y value. So, let y=1/2x+5 equal y=-2x. That means. -2x = 1/2x+5.
If you are given two points on the line, then you first need to find the slope of the line and then use the Point-Slope Equation and ONE of the given points to ...We then use AI to explain the calculation itself and answer common questions about it.

And then we are told a line goes through the-- OK, so same thing. The line goes through these points with the equation of a line. So the main idea here is, you only need 2 points for an equation of line. They've given us more than necessary. So I'd like to pick the two points that make things a little bit simpler. So I'll pick the point 4, 2 ...Finding y-intercept of linear equation with two points. If we were given two points on a linear equation (x1,y1), (x2,y2) ( x 1, y 1), ( x 2, y 2), it is quite easy to find the slope and use substitution to find the slope intercept form y = mx + b y = m x + b, to graph it.

2 Answers. The equation must be of the form a(x − h2)(x − h) a ( x − h 2) ( x − h) with a ≠ 0 a ≠ 0. Using the point (0, 1) ( 0, 1) we get that. so a = 2/h2 a = 2 / h 2 (assuming that h > 0 h > 0 ). You are close. The quadratic is of the shape y = A(x − h/2)(x − h) y = A ( x − h / 2) ( x − h), where A A is a constant.
Jan 18, 2024 · We will assume you know two points that the straight line goes through. The first one will have coordinates (x₁, y₁) and the second one (x₂, y₂). Your unknowns are the slope m and the y-intercept b. Firstly, substitute the coordinates of the two points into the slope intercept equation: (1) y₁ = mx₁ + b (2) y₂ = mx₂ + b
In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.. There are basically two intercepts, x-intercept … We get the y-intercept by using the equation of a straight line which is; y = mx + b. Where; m is the gradient of the slope; b is the y-intercept. We can use the following formula to calculate the y-intercept. y – a = m ( x – b ) a and b being a point on a line. Example 1: Suppose you have a straight line whose gradient is 3 and a point 2,1 ...

The equation point slope calculator will find an equation in either slope intercept form or point slope form when given a point and a slope. The calculator also has the ability to provide step by step solutions.3 --> y = mx + b =. y = 3x + b. 3. Plug the points of the midpoint into the line. You already know that the midpoint of the points (2, 5) and (8, 3) is (5, 4). Since the perpendicular bisector runs through the midpoint of the two lines, you can plug the coordinates of the midpoint into the equation of the line.As Anand said, the question is vague. However, two important points for any equation are the x and y intercepts. For y = 2x, the x-intercept is (0,0) and the y-intercept is (0,0). Not sure if that helps. When finding the y-intercept, plug in x=0 y = 4x + 2 y = 4 (0) + 2 y = 2 So your intercept is (0,2) Find the Straight line equation if y-intercept is 6 and slope is 4. Solution: Step 1: Identify the values. b = 6. m = 4. Step 2: Write the slope form equation and place the values. y = mx + b. y = 4x + 6. If you need to calculate the slope using two points, use slope calculator. Here's how to find the two x-values for lines that intersect at two points: Example (factoring): We ended up with the equation. ( x − 2 ) ( x + 3 ) = 0 {\displaystyle (x-2) (x+3)=0} If either of the factors in parentheses equal 0, the equation is true. One solution is. x − 2 = 0 {\displaystyle x-2=0} →. This tells you that the y-intercept is 3. Since any point along the y-axis has an x-coordinate of 0, the form of any y-intercept is \((0, c)\) for some number \(c\). Using algebra to find the y-intercept of a function. To find the y-intercept of a function, let \(x = 0\) and solve for \(y\). Consider the following example. Example Instructions: Use this calculator to find the y-intercept of a line, showing you the process step-by-step. The first thing you need to do is to indicate the line you want to the y-intercept of. You have several options to state the line.

Finding the equation of the line using the points (3,8) and (8,3) [SLOPE INTERCEPT] 1. Find the slope between these points which is -1. Equation then becomes y=-x+b. Example 1. Notice that the graph in Figure 1, the graph of y = 4 x − 6, is a linear function that touches the y-axis at the point ( 0, − 6). Thus, the y-intercept of the …Slope intercept form is y=mx+b. Really, it is more like "Rise/Run Slope of a line from the y-intercept form". If you want to know the x-intercept form you can solve the equation for x. y=2x+4 would become x=1/2y-2. Now plug in zero for y and you will have what x is equal to (-2). The reason we use y=mx+b is because the idea of rise/run no ...Mar 1, 2022 · Intercepts from point-slope form. To begin, let’s determine x and y intercepts using point-slope form. We will begin with an equation: y+2=\frac{1}{2}(x-4) To determine the x-intercept, we must set the value of y equal to zero.

The y-intercept will be a point that will have a y coordinate and its x coordinate will be equal to zero. The coordinates of the y-intercept will be of the form (0, y). ... -6/5) = (0, - 1.2) Example 2: Find the y-intercept for given equation 1.3x + 0.6y - 2.4 = 0 and verify it using the online y intercept calculator. Solution: Given equation ...y = 3x + 2. y = 4x - 9. We must find a point (x,y) that satisfies both linear expressions. To find such a point, we must solve the linear equation: 3x + 2 = 4x - 9. To do this, we must write the variable x to one side, and all terms without x to the other side. So the first step is to subtract 4x on both sides of the equal sign. Recall that in the general slope-intercept equation y = m x + b , the slope is given by m and the y -intercept is given by b . Therefore, the slope of y = 2 x + 3 is 2 and the y -intercept is ( 0, 3) . In order to graph a line, we need two points on that line. We already know that ( 0, 3) is on the line. Additionally, because the slope of the ... Step 1: Find the slope (m). Use the formula to find the slope between the two points. Once you know the slope, plug it in for m in y = mx + b. This gives you y = 3x + b. Step 2: Find the y-intercept (b). Pick one of the points on the line and use the x and y values to find b.
