Answer:

The answer is choice C (-1, -2).

Step-by-step explanation:

For these types of problems, you need to substitute values into the equation for x and y.

Let's first try (1,2)

6x - 5y = 4?

6(1)-5(2)=4?

6-10=4?

-4≠4

So, A is not correct.

Let's try (1, -2)

6x - 5y = 4?

6(1)-5(-2)=4?

6+10=4?

16≠4

B is not correct either.

Let's try (-1, -2)

6x - 5y = 4?

6(-1)-5(-2)=4?

-6+10=4?

4=4!

Thus, the answer is choice C (-1, -2).
