Question

The points (8,1) , (3,-4) and (2,-5) are collinear.

• A. True
• B. False

Answer 1

The correct option is A True

Consider the given points.

$A(8,1),B(3,-4),C(2,-5)$

If these three points are collinear, then slope of two pairs of points will be equal.

Slope of $AB=\frac{-4-1}{3-8}=1$

Slope of $BC=\frac{-5+4}{2-3}=1$

Slope of $CA=\frac{1+5}{8-2}=1$

Hence, the slope is the same. Hence, these three points are collinear.
