Hi everyone! I'm doing a past paper and I'm stuck on this one:
ABC is an isosceles triangle such that AB = AC, A has coordinates (4,37), B and C lie on the line with equation 3y = 2x + 12.
Find an equation of the line of symmetry of triangle ABC.
Give your answer in the form px + qy = r where p, q and r are integers. Show clear algebraic working.
