Questions 1) The midpoint of AB is at M(0,3). If A=(0,−2), find B.
\n" ); document.write( "----
\n" ); document.write( "No change in x, makes it simple.
\n" ); document.write( "Distance from M to A is 5 units.
\n" ); document.write( "Add 5 to M --> (0,8)
\n" ); document.write( "=======================
\n" ); document.write( "Questions 2) Write the equation of the circle centered at
\n" ); document.write( "C(0,−6) that passes through P(−5,−18).
\n" ); document.write( "----
\n" ); document.write( "Find the distance from C to P, that's the radius r.
\n" ); document.write( "r^2 = diffy^2 + diffx^2 = 12^2 + 5^2 = 169
\n" ); document.write( "------------
\n" ); document.write( "\"%28x-0%29%5E2+%2B+%28y%2B6%29%5E2+=+r%5E2+=+169\"
\n" ); document.write( "\"x%5E2+%2B+%28y%2B6%29%5E2+=+169\"
\n" ); document.write( "
\n" );
