Question

Check (8,1),(3,-4) and ( 2,-5) 1 point
are collinear or not?
O Non-collinear
O collinear
O Both
O None of these​

Answer 1

Answer: Consider the given points.

A(8,1),B(3,−4),C(2,−5)

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

The slope of AB=3−8−4−1​=1

The slope of BC=2−3−5+4​=1

The slope of CA=8−21+5​=1

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

So, Option 2 is correct.
