Answer:

(-2,7)

Step-by-step explanation:

Remember: (x, y), Substitute the numbers:

1. (-3, 6)

5 • -3 + 4 • 6 = 18

-15 + 24 = 18

9 = 18 X, incorrect

2. (2, 4)

5 • 2 + 4 • 4 = 18

10 + 16 = 18

26 = 18 X, incorrect

3. (8, 2)

5 • 8 + 4 • 2 = 18

40 + 8 = 18

48 = 18 X, incorrect

4. (-2, 7)

5 • -2 + 4 • 7 = 18

-10 + 28 = 18

18 = 18, ☆, correct!
