Answer:
The answer is x=-5
Explanation:
In order to determine the equation, we need to know about vertical line equations.
In general, a line equation has the form:
Where "y" is the dependent variable, "x" is the independent variable, "m" is the slope of the line and "n" is the value where the line cuts the "y" axis.
A vertical line, x only takes one value. Thus, the equation for a vertical line is x = a, where a is the value that x takes.
So for the coordinate (-5,-1), the vertical line has to pass through the "x" value, that it is -5, therefore the equation of a vertical line passing through the point (-5,-1) is:
x=-5
