Answer:
undefined slope
Explanation:
(2,-3),(2,13)
notice how u have the exact same x values....this means that u have a vertical line where no matter what value y is, x will always be 2. Vertical lines have undefined slopes.
the equation for this line would be : x = 2
and just so you know, if the y values would have been the exact same, instead of the x ones, u would have a horizontal line with a slope of 0
