Answer:
-7 = the only yes
Step-by-step explanation:
You could solve this by using substitution (inputting the values of x into the equation and see if it equals the output, y = -43).
6(-2) - 1 = -43?
-12 - 1 = -43
-13 = -43 (false)
-2 = no
------------------------------------
6(5) - 1 = -43?
30 - 1 = -43
29 = -43 (false)
5 = no
6(-7) - 1 = -43?
-42 - 1 = -43
-43 = -43 (true)
-7 = yes
6(9) - 1 = -43?
54 - 1 = -43
53 = 43 (false)
9 = no
