3x - y = 1
3x - y = 2
Answer by tutorcecilia(2152) (Show Source): You can put this solution on YOUR website!
3x - y = 1 [Solve for y]
3x-3x-y=-3x+1
-y=-3x+1
-y/-1=-3x/-1 + 1/-1
y=3x-1
Plot the line with a slope of 3 and a y-intercept of (-1)
.
.
3x - y = 2 [Solve for y]
3x-3x-y=-3x+2
-y=-3x+2
-y/-1=-3x/-1 + 2/-1
y=3x-2
Plot the line with a slope of 3 and a y-intercept of (-2)
