What is the slope of the line that passes through the points ,minus, 5, minus, 9,(−5,−9) and minus, 5, minus, 13,(−5,−13)? Write your answer in simplest form
The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:
m = (y2 - y1) / (x2 - x1).
In this case, the points are (-5, -9) and (-5, -13).
So, the slope is:
m = (-13 - (-9)) / (-5 - (-5)).
m = (-13 + 9) / (-5 + 5).
m = -4 / 0.
The slope is undefined because the denominator is zero.
