## Intermediate Algebra (12th Edition)

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, $y=-2x ,$ has the following characteristics: \begin{array}{l}\require{cancel} \text{$y-$intercept: } 0 \\\text{slope: } -2 .\end{array} The $y-$intercept is at the origin. Since the slope is a negative number, then the line is inclined to the left. These characteristics are best exemplified by $\text{ Graph G .}$
