If the points (x ,\ -2),\ (5,\ 2) and (8...

If the points `(x ,\ -2),\ (5,\ 2)` and `(8,\ 8)` are collinear, find `x` using determinants.

Text Solution

Verified by Experts

Given that the points are collinear
So, area of the triangle formed by the points `=0`
`\Rightarrow \frac{1}{2}` `[[x , -2 ,1],[ 5, 2 , 1 ], [8 , 8, 1]] =0`
