Answer:
Undefined
Step-by-step explanation:
(see attached for reference)
in our case, we are given 2 points
(x₁, y₁) = (-9,-6)
(x₂, y₂) = (-9,-10)
immediately we can see that the x-ordinate for both points are the same, which means that if we were to draw a line through both points, it would form a vertical line.
By definition, a vertical line has a slope that is undefined (answer)

The slope of the given line is undefined.
The slope of line:
- If a line y = mx + c passes through [tex]A(x_1,y_1) \ and \ B(x_2, y_2)[/tex], then slope, m is given by [tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex] .
How to solve the given question?
- As the line passes through (-9,-6) and ( -9, -10),
The slope is given by,
[tex]m = \frac{y_2 -y_1}{x_2 - x_1} = \frac{(-10) - (-6)}{(-9) - (-9)} =\frac{-4}{0}[/tex] - ∴ Slope, m = undefined.
Thus, the slope of the given line is undefined.
