$y$=-$\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.
