Question 408409: determine whether the graphs of the pair of lines are parallel. x+7=y, y-x=-3. The slope of line x+7=y is? Answer by ewatrrr(24785) (Show Source):
Hi
x + 7 = y |slope m = 1 and y-intercept is Pt(0,7)
y-x=-3 OR y = x - 3 |slope m = 1 and y-intercept is Pt(0,-3 )
Lines are parallel as each with slope m = 1
