**Question: 510**

**9.** In the *xy*-plane, which of the following is a point of intersection between the graphs of *y* = *x* + 2 and *y* = *x*^{2} + *x* - 2 ?

A. (0, -2)

B. (0, 2)

C. (1, 0)

D. (2, 4)

E. (3, 5)

**Correct Answer:** D

**Explanation:**

**D** Test the answer choices. The first number in each pair represents *x,* and the second number represents *y*. The ordered pair should work in both functions. Try C in the first equation: Does 0 = (1) + 2? No. So, C is not the answer. Try D in the first equation: Does 4 = (2) + 2? Yes. So, try D in the second equation: Does 4 = (2)^{2} + 2 – 2? Yes. Because D works in both equations, it is the correct answer.
