Question

use the graph below to answer the questions
the slope of the line is
0
undefined

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 points on red - vertical line

For a vertical line like the red one in the graph, all points have the same x - value. Let two points on the line be $(x_1,y_1)$ and $(x_2,y_2)$ with $x_1=x_2$.

Step3: Calculate slope

Substituting into the slope formula, we get $m=\frac{y_2 - y_1}{x_2 - x_1}=\frac{y_2 - y_1}{0}$ (since $x_1 = x_2$), and division by zero is undefined.

Answer:

undefined
