Question

1. diagram of coordinate grid with vertical line m=

Explanation:

Step1: Identify the line type

The line in the graph is a vertical line. For a vertical line, the slope formula is $m = \frac{y_2 - y_1}{x_2 - x_1}$, but for a vertical line, $x_2 = x_1$, so the denominator is 0.

Step2: Determine the slope

A vertical line has an undefined slope because division by zero is undefined. So the slope \( m \) of a vertical line is undefined.

Answer:

undefined
