Points (-3,2) and (1,8) are endpoints of the diameter of a circle.
\n" ); document.write( "
\n" ); document.write( " (a) What is the length of the diameter? Give the exact answer, simplified as much as possible.
\n" ); document.write( "It's the distance between the 2 points.
\n" ); document.write( "\"d+=+sqrt%28diffx%5E2+%2B+diffy%5E2%29\"
\n" ); document.write( "----------------\r
\n" ); document.write( "\n" ); document.write( "(b) What is the center point C of the circle?
\n" ); document.write( "The midpoint between the 2 points.
\n" ); document.write( "-------------
\n" ); document.write( "(c) Given the point C you found in part (b), state the point symmetric to C about the x-axis.
