If two lines are perpendicular, their slopes are the inverse of each other and their signs are opposite.

Two lines are perpendicular if their directional vectors are perpendicular.

Determine the equation of the line that is perpendicular to r ≡ x + 2 y + 3 = 0 and passes through the point A = (3, 5).

Given the lines r ≡ 3x + 5y − 13 = 0 and s ≡ 4x − 3y + 2 = 0, calculate the equation of the line that passes through their point of intersection and is perpendicular to the line t ≡ 5x − 8y + 12 = 0

Calculate k so that the lines r ≡ x + 2y − 3 = 0 and s ≡ x − ky + 4 = 0 are perpendicular.
