Question

(c) Find the value of k if the points.
A (k + 1, 2k), B (3k, 2k + 3) and C(5k - 1,5k) are
collinear.​

Answer 1

Answer:

Area of triangle = o ,when given points are collinear

Step-by-step explanation:

Area of triangle = 1/2 [ k+1(2k+3-5k)+3k(5k-2k)+5k-1(2k-2k+3)=0. By solving it you get ,k=-5/2
