Answer: 5 units
Step-by-step explanation:
Add together the numbers, while making sure they are positive(if they aren't drop the negative).
Point C is in between the distance of 2 and 4. We see that the number in between is 3, so we add 3 to our final total.
Point D is on the line x=-2. Therefore, we convert the -2 to 2 to get:
3+2=5
Therefore, the answer is 5 units. :D
