Which of the following describes how to graph the line whose equation is y = x - 1? Plot the point (0, -1), move up 3 and right 2, plot the point, and draw the line through these 2 points. Plot the point (0, -1), move up 2 and right 3, plot the point, and draw the line through these 2 points. Plot the point (-1, 0), move up 2 and right 3, plot the point, and draw the line through these 2 points.

I think none of the choices would be correct. To plot the function given, we first plot the y-intercept which is (0,-1). Then, since the slope of the line is 1, we can move 2 units up and 2 units to the right or 3 units up and 3 units right starting from the y-intercept. None of the choices corresponds to this.
