Hey there!

The more accurate way to answer is:

Given points,

A ( 1 , - 3)

B ( 2, -5)

C ( -4, 7)

Slope of AB:

(y₂ - y₁)  / (x₂ - x₁)

= (-5 + 3) / (2 - 1)

= -2

Slope of BC:

(y₂ - y₁)  / (x₂ - x₁)

= (7 + 5) / (-4 - 2)

= 12 / -6

= -2

Since, Slope of AB = Slope of BC

Hence, the lines are collinear.
