No because the cost to ship a video game starts at 4.85 but if it were to start at zero than I would because it consistently adds 39.99.
X and y vary directily means
y=kx
72=3k
divide both sides by 3
24=k
k=24
y=72
Your answer will be y=-2/3x+4/3 and I believe I deserve the brainliest answer :))) Hope this helps!
