Answer:
Integers
Step-by-step explanation:
Counting Numbers are {1,2,3,4,5,...}
Its opposite would be -1,-2,-3,-4,-5,... respectively.
It includes 0 so the whole set would be
{ ..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, ... }
which is set of integers.
Idk what you mean but i from 7 and square root of 3 i got
12.12435565... as the decimal form
-9 ≤ y ≤ 8
look at the endpoints of the segment; (7, 8) and (-2, -9)
the y-values represent the range and they go from -9 to 8, inclusive
