Answer
$y$=-$\frac{2}{3}$$x$+5
Work Step by Step
Slope-intercept form: $y=mx+b$.
The slope is going downwards, so we know it is negative. We calculate the slope by using the $\frac{rise}{run}$ method. From point (0,5) to point (3,3), we move down 2 and right 3. So, the slope or $m$ value is $-$$\frac{2}{3}$. The y-intercept on the graph is at (0,5), so our $b$ value is 5.
