**Question: 491**

**11.**

Which of the following could be the equation of the line represented in the graph above?

A. *y* = 2*x* + 4

B. *y* = 2*x* – 4

C. *y* = –2*x* – 1

D. *y* = –2*x* – 4

E. *y* = –2*x* + 4

**Correct Answer:** E

**Explanation:**

**E** Remember that the equation of a line is *y* = *mx* + *b*, where *m* is the slope and *b* is the *y*-intercept. POE! The line in the graph has negative slope, so you can eliminate A and B, and it has a positive *y*-intercept, so you can eliminate C and D.
