PLEASE HELP 15 points An arrangement of helium balloons in the back of a delivery truck travels from a town at
the base of a mountain up the mountain where the air pressure is half the amount. What
do you expect to happen to the balloons?
a. The balloons will increase to twice their original volume.
b. The balloons will decrease to half their original size.
C. The balloons will increase to four times their original size.
d. The balloons will decease to one fourth their original size.

b. The balloons will decrease to half their original size.

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
