2Determine whether the given points are collinear(2) P(1, 2), Q02, ), R(3, 5)

Answer»

1) slope AB = (-0.5-2)/(1-0) = -2.5/1 slope BC = (-3+0.5)/(3-1) = -2.5/1 since they are equal , so collinear

2) slope PQ = (8/5-2)/(2-1) = -2/5 slope QR = (6/5-8/5)/(3-1) = -2/5 since they are equal , so collinear..
