Two pairs of perpendicular lines are lines that intersect at a right angle (90 degrees). For example, the x-axis and y-axis on a Cartesian coordinate plane are perpendicular to each other. Similarly, the lines represented by the equations ( y = 2x + 3 ) and ( y = -\frac{1}{2}x + 1 ) are also perpendicular, as their slopes multiply to -1.
