Graph E

Work Step by Step

Using $y=mx+b$ or the slope-intercept form of linear equations where $b$ is the $y-$intercept and $m$ is the slope, the given equation, $ y=-3 ,$ has the following characteristics: \begin{array}{l}\require{cancel} \text{$y-$intercept: } 3 \\\text{slope: } 0 .\end{array} The $y-$intercept is at the negative $y-$ axis. Since the slope is $0$, then the line is horizontal. These characteristics are best exemplified by $\text{ Graph E .}$
