Answer 2

Answer:

If three points are to be collinear then the slope of the lines formed by joining any two of them should be equal.

Let's check it out:

Let the points be: A(1,5),B(2,3),C(−2,−11)A(1,5),B(2,3),C(−2,−11)

here y2=3,y1=5 & x2=2,x1=1

Thus, slope of AB=

(2−1)

(3−5)

= -2

Now let's the slope of AC;

Slope AC=

(−2−1)

(−11−5)

=

3

16

Thus we see that the slope of AB &AC are not same therefore the points A,B &C are non-collinear.
