Answer

Graph A

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=2x+3 ,$ has the following characteristics: \begin{array}{l}\require{cancel} \text{$y-$intercept: } 3 \\\text{slope: } 2 .\end{array} The $y-$intercept is located on the positive $y-$axis. Since the slope is a positive number, then the line is inclined to the right. These characteristics best exemplify $\text{ Graph A .}$
