Question: 8

8. On a number line, point A is at -4 and point B is at 8. What point is 1/4 of the way from A to B?

A. -2
B. -1
C. 0
D. 1
E. 2

Correct Answer: B

Explanation:

B. You can draw the line and count spaces to determine that the points are 12 units apart, or you can simply subtract: 8 - (-4) = 12. (Distance always involves a difference.) 1/4 of 12 is 3, so you need to find the point 3 units to the right of -4; -4 + 3 = -1.
