Mark A=(-2,-1) and B=(2,2) and sketch the taxi cab ellipses on the same graph

I have done the taxicab with radius 9 but cant get the others to work out on the same graph?

#4 _#4 {(Pd_E (P_A)+d_E (P,B)=9)} (P\d (P, A) + d (P,B) = 9} point tab {P]d;(P, A) + d;(P,B) = 13} {P\d (P, A) + d (P,B) = 7} {P]d(P, A) + d (P,B)
