Question

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




​

Answer 1

Given points (1,5),(2,3)(−2,−1)

Lets find a equation of line passing through (1,5)(2,3)

→

x−1

y−5

=

3−5

2−1

→−2(y−5)=x−1

→−2y+10=x−1

→x+2y=11

Point (−2,−1)⇒−2+2(−1)=−4



=11

So, point (−2,−1) do uot passes through line all thsee points are not collinea

I hope this helps you
