Question

How do you graph `y=1/5x` by plotting points?

Answer 1

Please see below.

Explanation:

Let us select some values of `x` in multiples of `5`, such as `{-20,0,20}`

Corresponding values of `y` are one-fifth of that i.e. `{-4,0,4}`

So the three points on graph would be `(-20,-4)`, `(0,0)` and `(20,4)`.

As `y=1/5x` is a linear equation, hence straight line joining these points will give us the desired graph, which is like this

graph{x/5 [-20, 20, -10, 10]}
