Given the points (2,2) and (2,3), find the equation of the line passing through the two given points.
Let m = slope
m = (difference of y values in the points) divided by (difference of x values in the points)
m = (3 - 2)/(2 - 2)
m = 1/0 which does not exist since we cannot divide by zero.
Considering that the slope in this case is undefined, is the
line x = 2 correct? In other words, is the line vertical at x = 2?
