# What is the slope and intercept for y=9?

Nov 1, 2016

It is a horizontal line. The slope = 0.
The line cuts the y-axis at the point $\left(0 , 9\right)$

#### Explanation:

$y = 9$ is the equation of a horizontal line. The slope is 0.

If we write it in slope-intercept form we will have:

$y = 0 x + 9$

This means that for any value of $x$ that is chosen, the y-value is always 9 Hence $y = 9$.

The y-intercept is at the point $\left(0 , 9\right)$
