Question

verify that the points (1,5), (2,3) and ,(-2,-1) are collinear or not​

Answer 1

Answer:

Given points (1,5),(2,3)(−2,−1)

Let's find a  equation of line passing through (1,5)(2,3)

→  y−5 /x−1  =  2−1 /3−5

→ −2(y−5)=x−1

→ −2y+10=x−1

→ x+2y=11

Point (−2,−1)⇒−2+2(−1)=−4  not equal to 11

So,  point (−2,−1)  does not pass through line all these  points are not collinear.
