**Question: 503**

**2.**

The graph above shows *y* = 2*x*. Which of the following graphs represents *y* = |2*x*|?

A.

B.

C.

D.

E.

**Correct Answer:** B

**Explanation:**

**B** Try plugging in some values for *x* and see if the graphs include that point. If *x* = 0, then *y* = 0, so, (0, 0) should be a point on the graph. Unfortunately this doesn't eliminate anything. If *x* = 1, then *y* = 2, so, (1, 2) should be a point on the graph. Eliminate A, C, D, and E.
