Which of the following is a correct interpretation of the expression 2-(-7)? Choose 1 answer: A Start at 2 on the number line and move 7 to the left B Start at 2 on the number line and move 7 to the right (C) Start at -7 on the number line and move 2 to the left D Start at -7 on the number line and move 2 to the right

Simplify the expression: Let's first simplify the expression 2-(-7). Subtracting a negative is the same as adding the positive equivalent of that number. So, 2-(-7) becomes 2+7. Now, let's add the numbers. 2 + 7 = 9Subtracting a negative: Now that we have simplified the expression to 9, let's interpret the original expression in the context of a number line. The expression 2-(-7) effectively means starting at 2 and adding 7, because subtracting a negative number is the same as adding its positive counterpart. On a number line, adding 7 to 2 means moving 7 units to the right from the starting point of 2.
