it is given that the three points are collinear
so we need to equate the area of triangle formed by these three points to zero
we get one equation in a and b
now it is given that pq=qr
so we apply the distance formula
replacing value of a with b we get a quadratic equation in b which we can solve to get values of b
use equation one to get value of a
