Question

verify that the points (1,5),(2,3) and (-2,-1) are collinear or not? for class 10​

Answer 1

Step-by-step explanation:

Answer

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 collinear

Answer 2

Answer:

Given points (1,5), (2, 3) (−2, −1) Lets find a equation of line passing

through (1,5) (2,3)

y-5 2-1 X-1 3-5

→ −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 collinear.
