Question

Determine whether the following points are colinear a(-3,2) b(1,-2) c(-9,10)

Answer 1

Step-by-step explanation:

If the sum of any two distances out of d(A, B), d(B, C) and d(A, C) is equal to the third , then the three points A, B and C are collinear.

we will find d(A, B), d(B, C) and d(A, C).

Points A, B, C are collinear.
