You can put this solution on YOUR website! f(x) = -3x-2 is a straight line with y-intercept at -2 and with slope , which means a rise (down) -3 and run (right) of 1.
Start by graphing the point (0,-2) on the y-axis. From this point go DOWN 3 units, then RIGHT 1 unit, and put a second point. Connect the points, and that's the line.
