Question

for the graph on the right, determine if the slope is positive, negative, zero, or undefined. choose the correct slope. a. zero b. negative c. undefined d. positive

Explanation:

Step1: Recall slope formula

Slope $m = \frac{y_2 - y_1}{x_2 - x_1}$

Step2: Analyze vertical line

For a vertical line, $x_2 = x_1$, so $x_2 - x_1 = 0$.

Step3: Evaluate slope

Dividing by 0 is undefined, so slope is undefined.

Answer:

C. Undefined
