Answer:
(2b, 2b + 7)
Step-by-step explanation:
Let's remember that an ordered pair has the value of x on it first coordinate and the value of f(x) (or we can call it "y") in the second one.
We already know that the value of x is 2b, let's see what's the value of f(2b):
We just need to replace the x with 2b:
f(2b) = 2b + 7
Therefore, the ordered pair for the point on the graph when x = 2b is (2b, 2b + 7)
