A possible linear equation for line n is given as follows:
y = b. (in which b is any constant).
The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which the parameters are given as follows:
When two lines are perpendicular, the multiplication of their slopes is of -1. Additionally, the perpendicular line to a vertical line is an horizontal line.
Two points on line m are given as follows:
(5, -3) and (5, 7).
Meaning that it is a vertical line, as the x-coordinate is constant.
Thus the perpendicular line n is an horizontal line, which has the definition given as follows:
y = b. (in which b is any constant).
