y = 3x + 6\r
\n" ); document.write( "\n" ); document.write( "This line equation is in slope-intercept form so the slope of this line is 3. A line perpendicular to this line has a slope that is the negative reciprocal of 3 which is -1/3.\r
\n" ); document.write( "\n" ); document.write( "The equation of the perpendicular line must look like y = (-1/3) + b where b is the value of y when x is zero.
\n" ); document.write( "
\n" );
