Describe what a number line representing d > -4 would look like
1. hollow circle at -4 with an arrow extending to the right
2. hollow circle at -4 with an arrow extending to the left
3. solid circle at -4 with an arrow extending to the right
4. solid circle at -4 with an arrow extending to the left
The correct answer is option 3: solid circle at -4 with an arrow extending to the right.
This is because the symbol "d > -4" indicates that the variable d is greater than, but not equal to, -4. The use of a solid circle at -4 indicates that -4 is included in the solution set, and the arrow extending to the right shows that d can take on any value greater than -4.
