# How do you write the equation in point slope form of a horizontal line that passes through (-6,0)?

Dec 22, 2016

$y = 0 \text{ that is the x-axis}$

#### Explanation:

The equation of a horizontal line, parallel to the x-axis has only one form.

$\text{ That is } y = c$ where c is the value of the y-coordinate that the line passes through. In this case zero.

$\Rightarrow y = 0 \text{ is the equation of the line }$ which is in fact the x-axis.
