THEN IT MUST BE A HORIZONTAL LINE
AND NOT AN INCLINED LINE

THEN I CANT HELP
BECAUSE AS I MENTIONED ABOVE IF T_I=T_F IS GIVEN
THEN P_I=P_F SHOULD BE THE CASE TO BE CONSIDERED

IF NOT THEN I AM MISSING SOMETHING DEARLY

the red line is the required curve

As T_i=T_f

initial and final points will lie on the curve PV=constant

P and V are linear

also PV=nRT

T_i=T_f

gives P_iV_i=P_fV_f

so i and f will both lie on PV=constant

join them with straight line as the required curve is linear
