Question

Prove that the points (-2,5) (0, 1) and (2,3) are
collinear.​

Answer 1

Step-by-step explanation:

Let the points be

A(-2,5)

B(0, 1)

C(2,3)

AB = √(0+2)^2+(1-5)^2 = √4+16 = √20

BC = √(2-0)^2+(3-1)^2 = √4+4=√8

AC = √(2+2)^2+(3-5)^2 = √4^2+(-2)^2 = √16+4=√20

Since AB = AC hence proved
