RECALL: A horizontal line has a slope of zero and an equation of the form $y=k$ where $k$ is the y-intercept. All points on the line have $y=k$. The given line is horizontal and contains the point $(-3, 2)$. This means that all points on the line have $y=2$, and that the equation of the line itself is $y=2$. Thus, the equation of the line is: $\color{blue}{y=2}$
