Question

Which number line model represents the expression 6+(−2)6+(−2)?

a) -8
b) -6
c) 4
d) 8

Answer 1

The number line model that represents the expression 6+(−2)6+(−2) is option c) 4.

Step-by-step explanation:

The expression 6+(−2)6+(−2) can be simplified by performing the addition operation. A number line model is a visual representation of numbers on a horizontal line. To add two numbers with different signs, we subtract the number with the negative sign from the number with the positive sign. The point where we end up is the result of the expression, which is 4. In this case, we have 6+(−2), which is equal to 6-2, which equals 4. Therefore, the number line model that represents the expression 6+(−2)6+(−2) is option c) 4.
