How do you work out the midpoint of the line? And then how do you work out the perpendicular line? Also could you add explanation to points?

A straight line passes through the points A(1, 4) and B(5, 16). Find the equation of the line perpendicular to AB that passes through the midpoint of AB.

Mid point (3 , 10) m AB = 12 / 4 = 3 m perp = - 1/3 y - 10 = (-1/3) ( x - 3 ) y = (-1/3) x + 11
