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.
Answer:

<h3><u>x=1 and x=</u><u>-</u><u>15</u> is the right answer.</h3>
Y=5x
y=12x^2
