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

Explanation

Equation of a line passing through the points `(3,0)` and `(-2,-2)` is
`y-0=(-2-0)/(-2-3)(x-3)`
`implies 5y=2x-6`
`implies 2x-5y-6=0`
for point `(8,2)`,
L.H.S `=16-10-6=0`= R.H.S
`:.` Point `(8,2)` also like on this line.
Therefore, given points are collinear.
