You get to choose the points so chose them so that the arithmetic is easy. I would first take $x = 0$ and substitute in the equation to get \[y = 2 \times 0  1 = 1\] and hence the point $(0, 1)$ is on the graph. Now choose another $x$ value, say $x = 1$ or $x = 2$ or $x = 1$ or some other value, substitute into the equation to obtain a second point on the graph. Graph this point also. Since the graph is a line use a ruler to draw the line that lies on these two points. If you don't recognize that the graph is a line you will need to plot more than two points. If you plot 4 or 5 points reasonably accurately then using a ruler you will see that the points lie on a line. Penny
