Answer:
9
Step-by-step explanation:
Plug in -2 for x, and -1 for y, and solve: 
3x - 4y + 11
3(-2) - 4(-1) + 11
Remember to follow PEMDAS. First, multiply. Remember, that when you multiply: 
2 positive signs will result in a positive answer.
1 positive & 1 negative will result in a negative answer.
2 negative will result in a positive answer.
3 * -2 = -6
-4 * -1 = 4
-6 + 4 + 11 = 9
9 is your answer.
