Question

An object starts at position 12 on a horizontal line with a reference point of 0. What is the position of the object if it moves 14 units to the left?

Answer 1

At first it is at 12

It moves 14 to the left then

12-14=-2

Answer 2

Answer: B. -2

Explanation: 12 is on the RIGHT side (positive number line). Since the object moves 14 units to the LEFT, you're going to do 12 - 14 = -2.
