Answer:
Line M - neither
Line N - parallel
Line P - perpendicular
Line Q - neither
Step-by-step explanation:
If a line is perpendicular to another, the slope will be the opposite, e.g. -6, opposite slope, -6.
If a line is parallel to another, the slope will be the exact same, e.g. -6, same slope, 1/6.
-4/3 -5/1= 120 so if you add them they equal 120 which is -120
The rule of product states that:
So, a product is positive if and only if both factors have the same sign, and is negative if only if the factors have opposite sign.
