How do you find the slope of  y=5?

Apr 27, 2016

The slope is zero.

Explanation:

You might immediately see that this equation represents a perfectly horizontal line that will have slope zero (neither increase nor decreases).
Also, in terms of general form you can write it as:
$y = m x + c$ where $m$ is the slope; but in your case you have:
$y = 0 x + 5$ giving $m = 0$.

Graphically:
