Question

if (k,2),(2,3)and(3,4) are collinear then the value of k is​

Answer 1

Step-by-step explanation:

k(3-4)+2(4-2)+3(2-3)=0

-k+4-3=0

k=1

this is your answer

Answer 2

The value of k is 1.

Step-by-step explanation:

Since we have given that

(k,2),(2,3)and(3,4) are collinear.

So, we know that slope of first two coordinates = Slope of other two coordinates.

So, it becomes,

$\dfrac{3-2}{2-k}=\dfrac{4-3}{3-2}\\\\\dfrac{1}{2-k}=\dfrac{1}{1}\\\\2-k=1\\\\2-1=k\\\\k=1$

Hence, the value of k is 1.
