Nope.
Natural numbers consist of 1, 2, 3, 4 and so on. Integers, on the other hand, include 0 and the opposites of natural numbers (negative values). Therefore not all integers are natural numbers. Some of them are though.
Answer:
(-1, -9)
Step-by-step explanation:
Recall that for 2 points (x1, y1) and (x2,y2)
the midpoints are given by
x ordinate =
y ordinate = 
In our case x1 = 8, y1 = -10, x2 = -10, y2=-8
x ordinate =
= [8 + (-10) ] / 2 = -1
y ordinate =
= [-10 + (-8) ] / 2 = -9
hence midpoint is (-1, -9)
