The equation is .

Choose any four x values and substitute the equation .

let us chose four values are 1, 0, 1, 2.

The table is x and y values ordered pairs.

\   \	\ \	\   \	\ \
\   \	\   \	\   \	\   \
\   \	\   \		\   \
\   \	\   \	\   \	\   \

The solutions of the four ordered pairs are (1, 2), (0, 0), (1, 2), (2, 4).

The four ordered pair solutions are (1, 2), (0, 0), (1, 2), (2, 4).
