Line Width , Line Style , and Point Style bring up sub-menus that allow you to set their values. All these options can also be specified as parameters to the plot command. This menu allows you to choose how the axes are drawn. Boxed place the axes along the bounding box of the image and draws the box. Framed draws the axes along the bounding box, but does not draw the box.
None shows no axes.
The Projection menu specifies how the plot should be scaled in the window. Constrained shows the true scale of the plot. Unconstrained scales the plot to fit the window. Plot the solutions from Exercise 7 in one plot with different line styles.
