I know that if two lines have the same slope they will be parallel but what if a line has a slope of -4 and another has a slope of 4 will they also never intersect?

OpenStudy (mertsj):

No. They will intersect.

OpenStudy (mertsj):

Only if they are parallel will they not intersect.

OpenStudy (waheguru):

Why? Can you draw it for me

OpenStudy (anonymous):

No they will intersect since one has a positive slope and the other one a negative slope.

OpenStudy (mertsj):

Suppose we have two lines: y = 4x and y = -4x
