Question

1. diagram of coordinate grid with vertical line m=

Explanation:

Step1: Identify the line type

The line is vertical (parallel to the y - axis). For a vertical line, the slope formula \(m=\frac{y_2 - y_1}{x_2 - x_1}\) has a denominator of \(x_2 - x_1 = 0\) (since all x - coordinates on a vertical line are the same), and division by zero is undefined.

Step2: Determine the slope

By the definition of the slope of a vertical line, the slope \(m\) is undefined.

Answer:

undefined
