The graph is below

*The equation is already arranged in the y=mx+b form.To graph, you start by plotting the y-intercept which is the b-value. You plot the point (0,-1) and then look at the slop. In this equation the slop is 2 and it is positive and since slope is rise over run, you go up 2 units and right 1 to graph the equation y=2x-1.
