See explanations.

Work Step by Step

Step 1. Given $f(x)=\frac{2}{3}x-2$, we can identify its slope as $m=\frac{2}{3}$ and y-intercept as $y=-2$ or point $(0,-2)$ Step 2. To graph the function, start from the first point $(0,-2)$, move 2 units up and then 3 units to the right to get the second point on the line. Step 3. Connect the two points to get the graph of the line.
