Answer:

B. Start at -7 on the number line and move 11 to the right.

Step-by-step explanation:

Given:

  • - 7 - (-11) expression

We can add or remove only positive numbers on the number line to get it  correct, so we need to open the parenthesis. When evaluated we get:

-7- (-11) = - 7 + 11 = 4

Correct interpretation of of this expression is:

  • Start at -7 and add 11, thus move 11 points to the right, to get 4 as final point.

Correct choice is:

  • B. Start at -7 on the number line and move 11 to the right.
