Patsy built a rectangular-prism-shaped trough for her horses to eat from. The trough is 4 meters long, 2 meters wide and 2 meters high. How much hay can the trough hold?

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
