What is the slope of the line that passes through the points left bracket, minus, 9, comma, minus, 9, right bracket(−9,−9) and left bracket, minus, 9, comma, minus, 7, right bracket(−9,−7)? Write your answer in simplest form
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:
slope = (y2 - y1) / (x2 - x1)
In this case, the coordinates of the points are (-9, -9) and (-9, -7). Plugging these values into the formula, we get:
slope = (-7 - (-9)) / (-9 - (-9))
= (-7 + 9) / (-9 + 9)
= 2 / 0
Since the denominator is zero, the slope is undefined.
