    Graph each plane in three dimensions. Homework Help ✎

  1. Solve for each intercept. You can do this by substituting for two of the variables and solving for the remaining variable.

      
                                    
                                     

      
                                
                                   

      
                                    
                                     

    Now that you know the , , and -intercepts, plot the points, connect them, and shade them to look like a plane.

  1. Solve for the intercepts like you did in part (a).
    Note that there is no -intercept.
