Answer 1

Answer: The points are collinear

Step-by-step explanation:

Answer 2

Step-by-step explanation:

ANSWER

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=

3−8

−4−1

=1

Slope of BC=

2−3

−5+4

=1

Slope of CA=

8−2

1+5

=1

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