Answer:
A: y= 1.5x -1
B: y= 1.5x + 0
Step-by-step explanation:
The formula to find slope is y=mx+b, m being the slope and b being the y intercept.
In A, the line shown passes through -1 on the y axis.
The slope is 1.5. An easier way to see that is to grab two points on the line and do this: (y2-y1 over x2-x1) It can be any points you like, as well.
I will use (2, 2) and (-2, -4), as these points are both found on the line, and they are exact.
So, first we will do this: we will take the two ys, y1 and y2. You don't have to do it like that, but sometimes it is easier just to take the higher value first. BUT! You do have to do it y over x, not x over y. Watch:
2- -4 = 6
____ ___
2 - -2 = 4
So your slope is 6/4 OR it is 1.5.
So for b, if they are asking you to create an equation with the same slope but it goes through the origin, then your next equation would be y= 1.5x+0. Since the original is represented by (0, 0), then you will have the y axis and y intercept at 0.
I hope this helps you!
