How to find the y intercept when given 2 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.

Let me further explain using my example in 3 straightforward steps: Step 1: You take the ordered pairs (2,9) and (19,10) and take out the y2 and y1 numbers. That would be 10 and 9. Then take out the x2 and x1 numbers. That should be 19 and 2. Step 2: Next, you should minus the y2 and y1 numbers from each other. 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. 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 ...Here are the steps to find the slope of a line given two points on it.

X=0. So x intercept is (0,0) So the x intercept and y intercept are actually the same points, the origin. Now we need one more point to graph the line chose any value for x and determine the value for 5. If we take x as 1, we get y=-2. If we take x as -1 we get y=2.Let me further explain using my example in 3 straightforward steps: Step 1: You take the ordered pairs (2,9) and (19,10) and take out the y2 and y1 numbers. That would be 10 and 9. Then take out the x2 and x1 numbers. That should be 19 and 2. Step 2: Next, you should minus the y2 and y1 numbers from each other. We're given a table of values and told that the relationship between x and y is linear. Then we're asked to find the intercepts of the corresponding graph. The key is realizing that the x -intercept is the point where y = 0 , and the y -intercept is where x = 0 . The point ( 7, 0) is our x -intercept because when y = 0 , we're on the x -axis. You want to get y by itself on one side of the equation, so you need to divide both sides by 2 to get y = 3x - 6; This is slope intercept form, y = 3x - 6.
