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.
