Question

use the number line to help solve the problem.
subtract -4 - 2
6
-6
2
-2

Explanation:

Step1: Recall subtraction on number line

To subtract \( -4 - 2 \), we can think of it as starting at \( -4 \) on the number line and moving 2 units to the left (since subtracting a positive number means moving left on the number line).

Step2: Perform the operation

Mathematically, \( -4 - 2 = -4 + (-2) \) (because subtracting a number is the same as adding its opposite). When we add two negative numbers, we add their absolute values and keep the negative sign. The absolute value of \( -4 \) is \( 4 \) and the absolute value of \( -2 \) is \( 2 \). So \( 4 + 2 = 6 \), and since both are negative, the result is \( -6 \).

Answer:

-6 (corresponding to the option " -6 ")
