Use the image to answer the question.
A number line with arrows at both ends ranges from negative 12 to 12. The numbers negative 12, 0, and 12 are labeled.
Solve the following equation: −4+8
. Use the number line as a model to find the solution.
To solve the equation -4 + 8 using the number line as a model, we start at -4 on the number line and then move 8 units to the right.
Starting at -4, we move 4 units to the right, which brings us to 0.
Then, we continue moving another 4 units to the right, which brings us to 4.
So, the solution to the equation -4 + 8 is 4.
To solve the equation −4+8 using the number line as a model, we start at -4 on the number line and move 8 units to the right.
Starting from -4, we move 1 unit to the right and reach -3. Then we move another unit to the right and reach -2. We continue this process until we have moved a total of 8 units to the right.
Following this process, we reach +4 on the number line after moving 8 units to the right from -4.
Therefore, the solution to the equation −4+8 is 4.
