$y = - 3$ $y = -3$

Explanation:

Generally, horizontal lines have the equation $y = k$ $y = k$ where $k$ $k$ is any constant.

Given that you have a horizontal line passing through $(5, - 3)$ $(5, -3)$ , we know that the only way for a horizontal line to satisfy this condition is if $y$ $y$ would be equal to $- 3$ $-3$ .

Hence we know that the equation of our horizontal line would be:
$y = - 3$ $y = -3$

Note that in determining the equation of a horizontal line, we can disregard the value of $x$ $x$ since we know that by drawing a horizontal line, we will be "touching" all the values of $x$ $x$ . In this case, just look at the $y$ $y$ coordinate of the given to know the equation of your horizontal line
