Equations of perpendicular lines

Straight line graphs

Algebra

Know that perpendicular slopes are the negative reciprocals of each other and give the equation of a perpendicular line when provided with either a given graph or equation in the form y=mx+b. (do not need m1 x m2 = -1). Identify perpendicular lines from only their equations by rearranging them in the form y=mx+b
