Find the equation of the perpendicular dropped from the point (-1, 2) onto the line joining the points (1, 4) and (2, 3).

Let P = (-1, 2) Let A and B be the points (1, 4) and (2, 3). We know that, Product of slope of perpendicular lines is -1. Let slope of line through P be m. ∴ m × Slope of AB = -1 ⇒ m × -1 = -1 ⇒ -m = -1 ⇒ m = 1. By point-slope form, Equation of line through P, ⇒ y - y 1 = m(x - x 1 ) ⇒ y - 2 = 1[x - (-1)] ⇒ y - 2 = 1(x + 1) ⇒ y - 2 = x + 1 ⇒ y - x = 1 + 2 ⇒ y - x = 3 ⇒ y = x + 3 Hence, equation of the perpendicular dropped from the point (-1, 2) onto the line joining the points (1, 4) and (2, 3) is y = x + 3.
