good job on A and B\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when you reflect a point over the x-axis; the x-values are unchanged, while the y-values change sign
\n" ); document.write( "(similarly, with reflection over the y-axis)
\n" ); document.write( "(reflection over the origin, causes BOTH signs to change)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "eg. ___ (3,2) reflected over the x-axis becomes (3,-2)
\n" ); document.write( "
\n" );
