I think you have the data wrong. This can be done but it is beyond the realm of high school mathematics...as given the graph, the line of symmetry and the directrix are oblique, that is, not lying in either horizontal or vertical directions...it involves an xy cross term...I doubt you have it correct...please check the problem and ask again...
