Answer:
y = 9
Explanation:
Given the value of x, which is 2, because the order pair given is (2, _), where the first digit correspond to x and the second digit correspond to y,
You have to plug number 2 in the given equation, replacing the x, in other words, substitute the given value for the variable.
So, y = 2(x) + 5
y = 2(2) + 5
Then, y = 9
