One you know that, if you graph two points on the line you can join them with a straight line to graph the line. For example if you substitute $x = 0$ into the equation to find the corresponding $y$ value, say $y = ?$, you can plot the point $(0, ?).$ Then try $x = 1$ to find a second point to plot and then join the points using a ruler. Another technique is to use the fact that $y = 2x  1$ is in the form $y = mx + b$ with $m = 2$ and $b = 1.$ Hence the slope of the line is 2 and the yintercept is $(0, 1).$ Penny
