perimeter =48
18+18+6+6=48
x-12=x/3
Multiply both sides by 3
3x-36=x
3x=x+36
2x=36
x=18
18-12=18/3
6=6
One side 18 another side 6
Basically here all you want to do it substitute the values x=1 and x=2 for the given function. Use your slope formula
.
Do same for x=3 and x=4
You next divide plug in values in to this expression:

Answer:y=-3x+10
