A "super ball" dropped from a height of x feet bounces to a height y that is 80% of x.

Can anyone please teach me how to find its numerical, algebraic, and graphical representations? Thanks a lot!!!

y is 80% of x. you can write as

y = 0.8x since 80% = 0.8

for example,if x is 20m high, when the ball drops, and bounces back then y will be 0.8(20) = 16m

is it the numerical, algebraic, or graphical representations?
