Question

find the slope of the line y = -1. write your answer as an integer or as a simplified proper or improper fraction.

Explanation:

Step1: Recall slope of horizontal line

A horizontal line has the equation \( y = k \) (where \( k \) is a constant). The slope of a horizontal line is 0 because the change in \( y \) (\( \Delta y \)) is 0 for any change in \( x \) (\( \Delta x \)), and slope \( m=\frac{\Delta y}{\Delta x} \).

Step2: Identify the line type

The line \( y = - 1 \) is a horizontal line (since it has the form \( y=k \) with \( k = - 1 \)). So its slope is 0.

Answer:

0
