    Do you know how perpendicular lines are related to eachother?

    It has to do with their slopes.

    I will tell you. Their slops are negative reciprocals of eachother. So if line 1 has a slope \(\frac{a}{b}\) then a perpendicular line 2 would have a slope of \(\frac{-b}{a}\)

    So what is the slope of the line you've been given?
