Question 973190
When calculating the midpoint of the points (3,1) and (11,7), what is the midpoint?
<pre>
It's just a matter of:

1. averaging the two x-coordinates.
2. averaging the two y-coordinates.

The average of the two x-components is {{{(3+11)/2=14/2=7}}}.
The average of the two y-components is {{{(1+7)/2=8/2=4}}}

So the midpoint between (3,1) and (11,7) is (7,4).  See?:
