Using linear function concepts, it is found that the slope of a line parallel to the line whose equation is y - x = 5 is of 1.
A linear function is modeled by:
y = mx + b
In which:
In this problem, we want a parallel line to y - x = 5. In slope-intercept format, the equation is:
y = x + 5.
The slope is of m = 1, hence the parallel line also has slope of 1.
