a. –6
b. 9
c. –12
d. 15
Answer : c
Explanation :
In Math, Integers are placed on a number line in marked, evenly spaced sections. A Zero divides this line into two segments. The positive integers appear on the right hand of the zero while the negative segments appear on the left hand of the zero. Each segment goes on to infinity therefore only the needed segment of the line is shown for each different math problem. The number line is a good tool to use when learning addition and subtraction of positive and negative integers. This will be covered in a different problem.
The above problem is a graphing problem showing the number line and requesting the identification of the value of a certain variable (in this case B) which is located on this line. A thorough examination of the line determines that the point B is located just above the integer
(-12). Therefore, the answer is ( c ) which is –12.
