Question 883631
The ednpoint of a diameter of a circle is (-1,6). If the center is at (2,-1), find the other endpoint of the diameter passing through (-1,6)
<pre>
Use the midpoint formula: ({{{(x[1] + x[2])/2}}},{{{(y[1] + y[2])/2}}}), equating each coordinate to the midpoint coordinates to determine
the other endpoint. Remember that you're trying to find {{{x[2]}}} and {{{y[2]}}}.
Then do a check!! 

If you need a complete and detailed solution, let me know!!
