Possible Answers:

\displaystyle 44

\displaystyle 45

\displaystyle 41

\displaystyle 42

\displaystyle 43

Correct answer:

\displaystyle 42

Explanation:

In order to solve this question, we need to use both the equation and the table. We are looking for the corresponding \displaystyle y value for \displaystyle x=3. We can plug \displaystyle 3 into the \displaystyle x in our equation to solve for \displaystyle y.

\displaystyle y=13(3)+3

\displaystyle y=39+3

\displaystyle y=42
