Question

what is the slope of this line?

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.

Step2: Identify two points

The two points on the line are $(7,1)$ and $(7,3)$. Let $(x_1,y_1)=(7,1)$ and $(x_2,y_2)=(7,3)$.

Step3: Substitute into formula

$m=\frac{3 - 1}{7 - 7}=\frac{2}{0}$. Division by zero is undefined.

Answer:

undefined
