what is the slope of the line that passes through the points (-9, -2) and (-9, -6)? write your answer in simplest form.
Answer
Explanation:
Step1: Recall slope - formula
The slope formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1=-9,y_1 = - 2,x_2=-9,y_2=-6$.
Step2: Substitute values into formula
$m=\frac{-6-(-2)}{-9 - (-9)}=\frac{-6 + 2}{-9+9}=\frac{-4}{0}$. Since division by zero is undefined, the slope of the line is undefined.
Answer:
Undefined
