Let's begin - Equation of a Line Perpendicular to a Line The equation of a line perpendicular to a given line ax + by + c = 0 is bx - ay + λ = 0, where λ is constant. Proof : Let m 1 be the slope of the given line and m 2 be the slope of a line perpendicular to the given line. Then, m 1 = - a b But, m 1 m 2 = -1 for perpendicular lines. physicians elemental diet amazon
