Question

How do you graph `y=3` using slope intercept form?

Answer 1

A horizontal straight line through `(0,3)` or any other value of `x`.
`y=0x+3`

Explanation:

The equation of a straight line in line `(m)` and intercept `(c)` form is: `y=mx+c`

However, in this example `y` is independent of `x` so the slope is `0`. This equivalent to: `y=3 forall x in RR`

Or: `y=0x+3`

Hence, our graph is a horizontal straight line through `(0,3)` or any other value of `x`.
