y = mx + b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = 3x + b ... plug in the given slope m = 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = 3x + 4 ... plug in the given y-intercept of b = 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the answer is y = 3x + 4
\n" ); document.write( "
\n" );
