Solve the System by Graphing $$\left\{ \begin{array} { l } x = 7 \\y = - 3\end{array} \right.$$

Multiple Choice

Solve the system by graphing. If there is no solution or an infinite number of solutions, so state. Use set notation to
express the solution set.
- $$\left\{ \begin{array} { l } x = 7 \\y = - 3\end{array} \right.$$

A) infinitely many solutions; $\{ ( x , y ) \mid x = 7 \}$ or $\{ ( x , y ) \mid y = - 3 \}$
B) $\{ ( - 3,7 ) \}$
C) $\{ ( 7 , - 3 ) \}$
D) no solution; $\varnothing$
