Graph the line y = (-1/3)x + 2 on the xy axis like so

This line goes through (0,2) and (3,1). To get any point on this line, plug in a specific x value (like x = 0) into y = (-1/3)x + 2 and compute it to get the corresponding y value.

That's the entire graph shown above. We just want it graphed on the domain [-2,8]. So what we do is erase the portion to the left of -2 and to the right of 8

Basically we only graph if x is between -2 and 8 (inclusive to both endpoints)

Doing so gives us this final answer

Notice how the red endpoints are at x = -2 and x = 8. These endpoints are closed circles to signify that we are including the endpoints.
