# Chapter 2 - Section 2.2 - The Slope of a Line - 2.2 Exercises: 64

#### Answer

$m=0$

#### Work Step by Step

$\bf{\text{Solution Outline:}}$ To find the slope and the graph of the given equation, $y=-4 ,$ use the slope and graph of lines in the form $y=b.$ $\bf{\text{Solution Details:}}$ Since lines of the form $y=b$ (where $b$ is a constant) have a slope of $0,$ then the slope of the line defined by the given equation is \begin{array}{l}\require{cancel} m=0 .\end{array} The graph of lines in the form $y=b$ is a horizontal line that passes through the $y$-axis at $b.$
