3x + y -12 = 0
\n" ); document.write( "subtract 3x from both sides of =
\n" ); document.write( "y - 12 = -3x
\n" ); document.write( "add 12 to both sides of =
\n" ); document.write( "y = -3x + 12
\n" ); document.write( "the problem asks if the point (3,3) is on the line, substitute for x and y
\n" ); document.write( "3 = -3*3 +12
\n" ); document.write( "3 = -9 + 12
\n" ); document.write( "3 = 3
\n" ); document.write( "therefore the point (3,3) lies on the line y = -3x + 12
\n" ); document.write( "
\n" ); document.write( "
\n" );
