Slope: Parallel & Perpendicular Lines

Slope: Parallel & Perpendicular Lines perpendicular To determine if two lines are perpendicular, we need to multiply their gradients together If the lines are perpendicular to each other, the product of their perpendicular Parallel lines never intersect each other They are non-intersecting lines Perpendicular lines are two intersecting lines They intersect each other at right

perpendicular 1630s, very steep or perpendicular face of rock, from French précipice, from Latin praecipitium a steep place, literally

perpendicular Perpendicular Lines Consider the equation of the line is ax + by + c = 0 and coordinates are , the slope should be − ab If one line is perpendicular to this line, the
