Answer:
7
Step-by-step explanation:
In the line that goes from 0 to infinity and minus infiity you can calculate what is the distance from -5 to 2, you just have to count the spots and to do so we will use a line:
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
As you can see we just have to count the number we have to jump from -5 to 2, and those are 7 numers: -4 -3 -2 -1 0 1 2, so the distance between -5 and 2 is 7 units.
