Solution:
Consider the following equation for a line L:
[tex]y\text{ = x-5}[/tex]
According to this equation, the slope of this line is m=1. Now, to find the slope of a line parallel to the given line, remember that the parallel line will have the same slope as the given line. Then, the correct answer would be:
The slope of a line parallel to the given line is:
1
