Question

Line m has a linear equation of y = 2x + 1 and line t has a linear equation of y = -2x - 4.

Are the lines parallel, perpendicular, or intersecting?

Answer 1

They are intersecting

a) Not parallel because they share different slopes

b) Not perpendicular, they dont intersect creating a right angle. This is because neither of the slopes are a reciprocal of each other.
