Casio fx-9860G graphing help

hi,

im learning linear/quadratic simulataneous equations and would like to use this calculator to graph the equations similar to the following to G-solv the points of intersection.

has anyone any idea if it can be done on this calculator without rearranging the expressions.

thanks

attached: screen dumps of the calculator display for these functions (only half the circle is drawn) so using G-solv it just gives (3,3) and not (-3,-3).

theres other menus for conics that allows and but you can't draw linear expressions here at least i dont think you can. (last 2 images)
