if two lines are parallel and the slope of the lines is m,what is the product of their slopes?
what is (m)(m) ?
the product is two times m
When two lines are parallel, they have the same slope. Let's assume the slope of both lines is m.
To find the product of their slopes, you simply multiply the slopes together. Therefore, the product of the slopes of two parallel lines with slope m is m * m = m^2.
