question 74

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.
- $\left\{\begin{array}{l}x=8 \\x=-5\end{array}\right.$

• A) no solution; \(\varnothing\)
• B) \(\{ ( - 5,8 ) \}\)
• C) infinitely many solutions; \(\{ ( x , y ) \mid x = 8 \}\) or \(\{ ( x , y ) \mid x = - 5 \}\)
• D) \(\{ ( 8 , - 5 ) \}\)
