# How do you find the slope of  y - 4 = 6?

Apr 5, 2018

Slope $= 0$

#### Explanation:

$y - 4 = 6$

$\therefore y = 10$

That is $y = 10 \forall x \in \mathbb{R}$

Hence, $y = 10$ is a horizontal line parallel to the $x -$axis through the point $\left(0 , 10\right)$

Any a horizontal line parallel to the $x -$axis has a slope of 0.

We can see this on the graphic below.
