1. Write the addition modeled on the number line.
8 7 6 5 4 3 2 1 0 -1 -2 -3 -4 -5 -6 -7 X
a. -2+(-3)=
b. 0+(-3) = -5
c. -5+(-3) = -2
d. 3+ (-5) = 0

Answer 1

To model the addition on the number line, start at the given number and move in the direction of the second number. If the second number is positive, move to the right on the number line. If the second number is negative, move to the left on the number line.

Step-by-step explanation:

To model the addition on the number line, start at the given number and move in the direction of the second number. If the second number is positive, move to the right on the number line. If the second number is negative, move to the left on the number line. In this case, we are asked to write the addition modeled on the number line for -5 + (-3).

Starting at -5, we move three units to the left to get the sum -8.

So, the correct option is a. -2 + (-3) = -8.
