Question

2.
Find the value of 'm when the points (2,-3), (0, 1).
(m, m)
are collinear.​

Answer 1

Answer:

2(0,1)-3(0,1)

2-3= -1

Answer 2

Answer:

m=1/3

Step-by-step explanation:

(2,-3), (0, 1),(m, m)

If (x1,y1),(x2,y2) and (x3,y3) are collinear then

x1(y2-y3) +x2(y3-y1) + x3(y1-y2)=0

Putting all the values we get

2*(1-m)+0(3+3)+m(-3-1)=0

2-2m+0-4m=0

6m=2

m=2/6=1/3
