Question 691185: y = 5 - 3x
3x - y = 8
Rewrite each in Slope intercept form if not already. Then determine whether each pair of equations represents perpendicular lines. (showing steps). Thank you

You can put this solution on YOUR website!
y = 5 - 3x
y=-3x+5
3x - y = 8
-y=-3x+8
y=3x-8

These lines are perpendicular because the x multipliers
are reciprocals (-3,+3).
