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 point `(3,0)` and `(-2, -2)` also passes through point `(8, 2)`.
The equation of the line passing through points `(3,0)`, `(-2, -2)` is
`(y−0)=
frac{
(−2−0)}{(−2−3)}
​
(x−3)`

`
