<h2>
Step-by-step explanation:</h2>
In this problem we know the equation of a line, which is:

We also can write this equation as:

The slope of this line is
which is the slope of the line we are looking for because they're parallel. We also have a point
. Therefore, we can write this equation as follows:

From the figures below, the line in red is
while the line in blue is
and this line passes through the point (-5, -3)!
