Case1(C₁):- The parametric equation are .

                       (Substitute x = t)

\ x \	\   \	\ (x, y) \
\ 0 \	\ \	\ (0, 1) \
\ 1 \	\ \	\ (1, 0) \
\ 1 \		\ (1, 0) \

Case2(C₂):- The parametric equation are .

Add those two terms.

t	\   \	\   \	\ (x, y) \
0	\ \	\   \	\ (0, 1) \
	\ \	\   \	\ (1, 0) \
	\ \	\ \	\ (0, 1) \
	\ \	\ \	\ (1, 0) \

Case3(C₃):- The parametric equation are .

Add those two terms.

t	\   \	\   \	\ (x, y) \
0	\ \	\ \	\ (1, 0) \
	\ \	\ \	\ (0, 1) \
	\ \	\ \	\ (1, 0) \
	\ \	\ \	\ (0, 1) \   \

Case4(C₄):- The parametric equation are .

                       (Substitute y = t)

\ y \	\   \	\ (x, y) \
\ 0 \	\ \	\ (1, 0) \
\ 1 \	\ \	\ (0, 1) \
\ 1 \		\ (0, 1) \

Above parametric equations point are equal then graph the equations.

The solution is .
