By using the concept of equation of a line, prove that the three points `(3, 0)`, `( -2, -2)`and `(8, 2)`are collinear.

Explanation

In order to show that the points `(3, 0), (- 2, - 2) and (8, 2)` are collinear, it suffices to show that the line passing through points `(3, 0) and (- 2, - 2)` also passes through point `(8, 2).`


The equation of the line passing through points `(3, 0)` and `(- 2, - 2)` is


`(y - 0) = (-2 - 0)/(- 2 - 3) (x - 3)`


`y = (- 2)/(- 5) (x - 3)`
