Find the slope of the line containing these 2 points (-2,4) and (-2,-4)
To find the slope of the line passing through two points (x1, y1) and (x2, y2), use the formula:
slope = (y2 - y1) / (x2 - x1)
In this case, the points are (-2, 4) and (-2, -4).
slope = (-4 - 4) / (-2 - (-2))
= (-4 - 4) / (-2 + 2)
= (-8) / 0
Note that the denominator is 0, which means that the line is vertical. A vertical line does not have a slope as it is undefined.
