To find the slope, we can use the formula m = y change/x change. Since we already have 2 points, we can subtract the second coordinates from the first ones.
1. (-18-(-18))/(15-6) = 0/9 = 0. m=0x
2. (16-12)/0-8) = 4/-8 = -1/2. m = -1/2x
Hope this helps.

Answer:
L = 6, w = 2
Step-by-step explanation:
Let w = width of rectangle
Let L = length of rectangle
w = L - 4
Area of rectangle = Lw
L (L - 4) = 12
L^2 - 4L = 12
L^2 - 4L - 12 = 0
(L - 6)(L + 2) = 0
L - 6 = 0
L = 6 (the other option doesn't work because dimensions can't be negative)
w = L - 4
w = 6 - 4
w = 2
Double check
A = Lw
A = 6 x 2
A = 12
It matches so we are right.
