Answer:
Step-by-step explanation:
any point looks like this --> point A = ( x, y )
point 1 = (5,4)
point 2 = (-9, 2)
we are given these points and are asked what is the x coordinate that is in the middle
so find the distance between the two 'x' coordinates
5 - (-9)
5 + 9 = 14
that's the distance between the points , now chop that in half. so 7
now add 7 to negative 9
or subtract 7 from 5
either way gets -2
-2 is the mid point of the 'x' coordinate
