Given:
The three points are W(0,-2), I(2,0) and L(5,k).
To find:
The value of k for which the given points are collinear.
Solution:
We know that, three points are collinear if the area of the triangle formed by these three points is 0.


The three points are W(0,-2), I(2,0) and L(5,k). So,




Adding 6 on both sides, we get



Therefore, the correct option is E.
3.162 and 3.162. (3.162 is the rounded square root of 10)
