Explanation Given information: The given function is, g ( x , y ) = x x + y , c = − 1 , 0 and c = 2 Calculation: The given function is, g ( x , y ) = x x + y ……. ( 1 ) Substitute c for g ( x , y ) in equation ( 1 ) . c = x x + y …… ( 2 ) Substitute − 1 for c in equation ( 2 ) . 1 = x x + y x + y = x y = 0 …… ( 3 ) The general equation of straight line is given by is y = m x + c Compare equation ( 3 ) with general equation straight line. Equation ( 3 ) represents straight line
