Of the four choices given, which two, when written as a system, have a solution of (–4, 5)? A 2-column table with 4 rows. Column 1 is labeled x with entries negative 1, 2, 3, 5. Column 2 is labeled y with entries 2, negative 1, negative 2, negative 4. 2 x + y = negative 3 Negative 2 x + y = negative 3 A 2-column table with 4 rows. Column 1 is labeled x with entries negative 1, 2, 3, 7. Column 2 is labeled y with entries 0, negative 3, negative 4, negative 8. 2 x + y = negative 3 and A 2-column table with 4 rows. Column 1 is labeled x with entries negative 1, 2, 3, 5. Column 2 is labeled y with entries 2, negative 1, negative 2, negative 4. Negative 2 x + y = negative 3 and A 2-column table with 4 rows. Column 1 is labeled x with entries negative 1, 2, 3, 5. Column 2 is labeled y with entries 2, negative 1, negative 2, negative 4. 2 x + y = negative 3 and A 2-column table with 4 rows. Column 1 is labeled x with entries negative 1, 2, 3, 7. Column 2 is labeled y with entries 0, negative 3, negative 4, negative 8. Negative 2 x + y = negative 3 and A 2-column table with 4 rows. Column 1 is labeled x with entries negative 1, 2, 3, 7. Column 2 is labeled y with entries 0, negative 3, negative 4, negative 8. Mark this and return
