Question

determine the slope of the line.
the slope of the line is
try one last time

Explanation:

Step1: Recall slope formula

The slope formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2 - y_1}{x_2 - x_1}$. For a vertical line, the $x$-coordinates of all points on the line are the same.

Step2: Identify line type

The given line is a vertical line passing through $x=-4$. Let two points on the line be $(-4,1)$ and $(-4,2)$.

Step3: Calculate slope

Substitute into the slope formula: $m=\frac{2 - 1}{-4-(-4)}=\frac{1}{0}$, which is undefined.

Answer:

undefined
