What is the answer of the screenshot below, i cant understand what they mean.

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need

True or false look at the picture pls : /

Find the solution of this system of equation -7x+y=-20 9x-3y=36
