Question

How do you graph `x=8` by plotting points?

Answer 1

A vertical line `8` units to the right of the origin.

Explanation:

This is an odd graph.

Think about what it's saying: `x=8`. This means that NO MATTER WHAT, `x` HAS TO equal `8`.

Notice that `y` is not even mentioned in the equation. Therefore, `y` is irrelevant! The only thing that matters is that `x=8`.

Therefore, points you could plot would be anything in the form `(8,y)`. You could plot `(8,0),(8,-4),(8,61),` or `(8,-pi)`.

It would look like a vertical line:

Note that any graph `x=a` where `a` is just a number is a vertical line. Similarly, any graph of `y=a` is just a horizontal line.
