7x+7=28x 28x-7x=7 21x=7 x=3
7x is still the slope, no matter what x equals.
If x=2, then 7x = 14 and if y=5 then 4y=20.
7x-3=39 7x=42 x=6
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
5x-8 = x+125x-x = 8+124x = 20x=5
(x,7x)
y = -7x 0 = -7x 0 = x x-intercept point is (0, 0).
8x=7x-7 x=-7
7x+17 = 45 7x = 45-17 7x = 28 x = 4
