Question

Prove that the points (2, - 2), (- 3, 8)

and (- 1, 4) are collinear.​

Answer 1

Answer:

ANSWER

Slope of the line joining by the points (2,−2),(−3,8)=−3−28+2=−510=−2

Slope of the line joining by the points (−3,8),(−1,4)=−1+34−8=2−4=−2

Sloap of both the line is same.

Hence, (2,−2),(−3,8),(−1,4) are collinear.
