Graphing Equations with X and Y

• Step 1:  Plot the first point on the y-axis at (0, 3).

  
  

  Step 2:  From the starting point, go DOWN 2 : RIGHT 1 to plot the next point.
  

• Step 1:  Plot the first point on the y-axis at (3, 0).

  
  

  Step 2:  From the starting point, go DOWN 3 : RIGHT 1 to plot the next point.
  

• Step 1:  Plot the first point on the y-axis at (0, -3).
  
  Step 2:  From the starting point, go UP 2 : RIGHT 1 to plot the next point.

• Step 1:  Plot the first point on the y-axis at (0, 3).
  
  Step 2:  From the starting point, go UP 1 : RIGHT 2 to plot the next point.
