Any and her family were traveling during vacation. she looked at her watch at point 1 in the diagram below, and then again at point 2 in the diagram below. her mom told her how far they traveled, as noted below.

so if in 2 hours you drove 80 miles the in 1 hour you have to have driven 40 miles (80m/2h)

so you have to divide the 1200 miles by the 40mph to find out how many hours the trip will take (1200m/40mph=30h)

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
