Answer
Slope: $\frac{2}{3}$
Y-Intercept: $4$
See image for graph.
Work Step by Step
The $\text{slope-intercept}$ form of a linear equation is $y=mx+b$, where $m$ is the $\text{slope}$ and $b$ is the $y$-$\text{intercept}$. The given equation is $y=\frac{2}{3}x+4$. Since $\frac{2}{3}$ takes the place of the $m$, it is the $\text{slope}$. Since $4$ takes the place of $b$, it is the $y$-$\text{intercept}$. To graph this line, we make sure that it crosses the $y$-axis at $y=4$ and that the line goes up $2$ every time it goes 3 to the right.
