Pick a couple of points that are on the graph and connect them with a straight line on an y vs x graph. Make y axis the vertical axis.
When x = 0, y = 4.
That can be one of the points.
When y= 0, x = -2. That can be another one.
When x = 0, y = 4.
That can be one of the points.
When y= 0, x = -2. That can be another one.

This website, with an actual graph, may explain the procedure for plotting a single equation better than I can with just words.
