**Question: 555**

**12.** What is the distance between the *x*-intercept and the *y*-intercept of the line *y* = *x* - 6?

A. 9

B. 15

C. (approximately 9.43)

D. (approximately 10.82)

E. 15 + (approximately 25.82)

**Correct Answer:** D

**Explanation:**

**D** First find the *x*- and *y*-intercepts. The *y*-intercept is (0, –6). To find the *x*-intercept, replace *y* with 0: 0 = *x* ? 6; 6 = *x*; and *x* = 9. So, the *x*-intercept is (9, 0). Now create a triangle and use the Pythagorean theorem: 6^{2} + 9^{2} = 117. The distance between the *x*- and *y*-intercepts is .
