Three points P(h,k), Q (x,y) and R (x,y) lie on a line show that (h-x) (y-y)= (k-y) (x-x),
Asked by hrai7387 | 16 Jan, 2023, 07:36: PM Expert Answer Let (h.k) , (x1 , y1) and (x2 , y2 ) are three given points

slope of segment PQ = slope of segment QR = If P, Q and R on same line , then both the above slopes are equal and we have = By cross multiplication of above expression, we get Answered by Thiyagarajan K | 16 Jan, 2023, 08:39: PM
