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

Jul 11, 2017

$0$

#### Explanation:

the line $y = - 4$is a line parallel to the $x - \text{axis}$

therefore the slope/gradient is $0$

Slope =$0$

#### Explanation:

The equation only has a $y$-term and a number term, but if we write the equation in the slope/intercept form, $y = m x + c$
we get:

$y = 0 x - 4$

From this we see that the slope is $0$

The line $y = - 4$ is a horizontal line which only has a $y$-intercept at $- 4$.

There is no change in the $y$-values, so the slope is 0.
