(5,-3) and (0,9)
\n" ); document.write( "You have a right triangle with sides of x & y & an hypotenuse (distance) of c.
\n" ); document.write( "x=5-0=5
\n" ); document.write( "y=9+3=12
\n" ); document.write( "x^2+y^2=c^2
\n" ); document.write( "5^2+12^2=c^2
\n" ); document.write( "25+144=c^2
\n" ); document.write( "169=c^2
\n" ); document.write( "c=sqrt169
\n" ); document.write( "c=13 ans. for the distance between these 2 points.
