A laser beam on a rotating platform shines on a wall 5 meters away. If the platform spins at 1 rev/min, and the laser initially aiming at the closest point on the wall, how fast is the laser moving along the wall after 10 seconds

your answer would be fusion

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
