-12x + y = 21
\n" ); document.write( "y=12x+21
\n" ); document.write( "21 is the Y intercept.
\n" ); document.write( "Setting Y=0 & solving for x gives us the X intercept.
\n" ); document.write( "0=12x+21
\n" ); document.write( "12x=-21
\n" ); document.write( "x=-21/12
\n" ); document.write( "x=-7/4 ans. for the X intercept.
