In this question, they simply want you to find a pair of x and y-coordinates that would be valid in this equation.
We can take a random number for x, like, say, 3.
y = 2x + 6
y = 2(3) + 6
y = 6 + 6
y = 12
Since giving the value of 3 to x results in y being 12, we can safely say that the coordinates (3, 12) would be valid in this equation. Therefore:
(12) = 2(3) + 6
Let me know if you need me to explain anything.
