Answer 2

Number lines are used to represent numbers using regular interval

The step to evaluate the expression is:

D) Michael could rewrite the expression as -8 + -3 and move 3 spaces to the left.

The expression is given as:

$- 8 - 3$

This can also be expressed as:

$- 8 - 3 = - 8 + - 3$

The sign (i.e. minus) in front of 3 means that, Michael will count to the left

Because Michael has located -8 on the number line, he will need to count 3 spaces left of 8.

i.e. He will stop at -11

Hence. the step to evaluate the expression is:

D) Michael could rewrite the expression as -8 + -3 and move 3 spaces to the left.
