Multiple Choice

Provide an appropriate response.
-For a certain system of two linear equations, the solution set is $\{ - 9,5 \}$ , and $D = 9$ . Find the values of $D _ { x }$ and $D _ { y }$ .

• A) \(\mathrm { D } _ { \mathrm { X } } = - 1 ; \mathrm { D } _ { \mathrm { y } } = \frac { 5 } { 9 }\)
• B) \(\mathrm { D } _ { \mathrm { x } } = 45 ; \mathrm { D } _ { \mathrm { y } } = - 81\)
• C) \(\mathrm { D } _ { \mathrm { x } } = - 81 ; \mathrm { D } _ { \mathrm { y } } = 45\)
• D) \(D _ { \mathrm { X } } = - 9 ; \mathrm { D } _ { \mathrm { y } } = 5\)
