At the West Texas Balloon Festival, another hot air balloon is sighted at an altitude of 800 ft. but is descending at a steady rate of 30 feet per minute. What does the y-intercept represent?

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
