Part D Now, switch over to the Large Ball Drop Tracker and observe the graphs of vertical displacement against time (y vs. t) and of vertical velocity
against time (vy vs. t) for the large ball, using the same process you did for the small ball. What can you say about the vertical displacement and
velocity of the large ball?

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

the components of a vector are the parts of the vectors that are to each other.
