Thank you for providing the additional answers. However, the question only asks to solve the equation −8+9. The correct answer is 1.
To solve the equation −8+9, we can use the number line as a model.
Step 1: Start at the number −8 on the number line.
Step 2: Move 9 steps to the right since we are adding 9.
Step 3: The endpoint of our movement is the solution to the equation.
Looking at the number line, we can see that when starting at −8 and moving 9 steps to the right, we end up at the number 1.
Therefore, the solution to the equation −8+9 is 1.
To solve the equation -8 + 9, we can use the number line as a model.
First, find the number -8 on the number line. It should be located to the left of 0 and labeled.
Next, starting from -8, move 9 units to the right on the number line. Count each unit by moving to the adjacent number on the number line.
After moving 9 units to the right, you should land on the number 1. So, the solution to the equation -8 + 9 is 1.
Therefore, the correct response is:
