Question

What is the coordinate of the midpoint of GO¯¯¯¯¯¯?

The number line from minus four to four by increment of one and each tick mark is labeled. In this number line point minus four is also labeled as G, minus three is labeled as H, minus two is labeled as I, minus one is labeled as J, zero is labeled as K, one is labeled as L, two is labeled as M, three is labeled as N, and four is labeled as O.

Answer 1

clearly, the midpoint is at position zero on the number line. That is midway between -4 and +4.

Answer 2

ummhhh, if G = -4 and O = +4 , by common sense wouldn't the middle be 0 ?
or
you could count from -4 to 4 , that would give you 8. What is half of that?
so you would count 4 to the right from -4, where would you end up?

Answer 3

it is four units from G to zero
it is also four units from zero to O
so
zero (K) is the midpoint.
or
(4 - -4)/2 = 8/2 = 4 so midpoint is 4 units from G
-4 + 4 = 0

Answer 4

What is the midpoint of HN¯¯¯¯¯¯¯¯¯?
