Question

9 fill in the blank 1 point slope= choose your answer. choose your answer...

Explanation:

Step1: Recall slope formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$ for two points $(x_1,y_1)$ and $(x_2,y_2)$ on a line. For vertical lines, $x_1=x_2$.

Step2: Identify line type

The given lines are vertical. For vertical lines, the denominator $x_2 - x_1 = 0$ in the slope - formula.

Step3: Determine slope

Since division by zero is undefined, the slope of a vertical line is undefined.

Answer:

undefined
