Problem: Given these pairs of points, (5, 15) and (5, 9), find the midpoint, distance, slope, and equation of the line.
Solutions:

To find the midpoint, average the x coordinates and y coordinates. The midpoint is
 To find the (always zero or positive) distance, use the formula
 To find the slope, use the formula
(which means it is a vertical line, which has infinite slope)
 Since the line is vertical, there is only one x value that will give all y values. The equation for the line is
