Pick a number for x and put it into the equation. Use that number as the xcoordinate of your point, and use what you get from solving the equation as your ycoordinate of the point. Plot that point. Repeat this process a few more times, and then connect the dots.

8262017 That is called Cartesian plotting because it was invented by Rene Descartes. He was lying in a hospital bed when he noticed a fly crawling on the ceiling. It occurred to him that if the fly's position were determined by an equation relating y and x, then the fly's path would be a picture of that equation. So to plot an equation, you pick a convenient value for x and find the resulting value of y. Then you measure x units along one axis and y units along the other, and mark a point there.
