i am attempting to graph the piecewise function

Question

y=(-2/3)x-6 if -9<=x<-6
(1/3)x if -6<=x<0
(((x-3)^2)/9) + (((y-0)^2)/16)=1 if 0<=x<=6

on a ti 89 titanium. i believe you must use the when( feature, but i haven't a clue as to how. we are using transformations of piecewise functions and i wish to use this to check my graphs
