Answer:
undefined
Explanation:
slope = rise/run = (y2-y1)/(x2-x1)
= (-2-3) / (-4 - -4)
= (-5) / (0)
You can't divide by zero.
===>>> so the slope is undefined. These 2 points are both at x=-4. This means that at x=-4, there are 2 y values - - - >>> -2 and 3. The slope of a straight vertical line is undefined.
