\n" ); document.write( "Hi,
\n" ); document.write( " which of the following is an equation of a line whose slope is 0
\n" ); document.write( "slope m = (change in y) /(change in x)
\n" ); document.write( "Green Line, y = 3 has a zero slope (y value does not change)
\n" ); document.write( "
\n" ); document.write( " \n" ); document.write( "
\n" );
