what is the slope of the line that passes through the points (-9, -9) and (-9, -7)? write your answer in…

Explanation:

Step1: Recall slope formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$, where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line. Let $(x_1,y_1)=(-9,-9)$ and $(x_2,y_2)=(-9,-7)$.

Step2: Substitute values

Substitute the values into the formula: $m=\frac{-7-(-9)}{-9 - (-9)}=\frac{-7 + 9}{-9+9}=\frac{2}{0}$.

Step3: Determine the slope

Since division by zero is undefined, the slope of the line is undefined.

Answer:

Undefined
