Find the equation of a line that is parallel to the line x=-14 and contains the point (-5,8)

Since the line x = -14 is a vertical line, any line parallel to it will also be a vertical line. A vertical line has an equation of the form x = c, where c is the x-coordinate of any point on the line.

In this case, since the line needs to contain the point (-5,8), the x-coordinate of this point should be the value of c. Therefore, the equation of the line parallel to x = -14 and containing the point (-5,8) is:

x = -5.
