Question

How do you find slope and intercepts to graph `y-3=0`?

Answer 1

Slope `m=0` and intercept at `x=0, y=3`

Explanation:

This equation can be written, rearranging it, as `y=3`;
this represents an horizontal line (slope zero) passing through `y=3` on the `y` axis.
Graphically:
graph{0x+3 [-10, 10, -5, 5]}
