on a number line, G=8, and H=-3. if H is the midpoint of line GI, find the coordinate of I
--------
Draw a number line.
Plot G = 8 to the right.
Plot H = -3 to the left.
----
Note: H is in the middle between G and I.
So Plot I to the left of H.
-----
Equation:
(8 + I)/2 = -3
-----
8 + I = -6
I = -14
