A ball is dropped from a height of 12.50 m. How many seconds does it take for the ball to reach the ground?

well it is at 12.50 meters in the air and the gravitational pull is 9.8 making the equation t=v/d making it .78  seconds i think

Explanation:

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
