The slope of a line can be calculated using the formula:
slope = (change in y-coordinates)/(change in x-coordinates)
In this case, the two points given are (1, 5) and (1, -5).
Since the x-coordinate of both points is the same, the change in x-coordinates is 0.
The change in y-coordinates is -5 - 5 = -10.
Therefore, the slope of the line is:
slope = (-10)/(0)
Since the denominator is 0, the slope is undefined.
So, the correct answer is:
D) undefined
