\n" ); document.write( "The given line is y = (6/5)x-4; its slope is (6/5).

\n" ); document.write( "Parallel lines have the same slopes; perpendicular lines have slopes that are negative reciprocals.

\n" ); document.write( "(a) Every line parallel to the given line has an equation of the general form y = (6/5)x+b.

\n" ); document.write( "To find the equation of the line parallel to the given line through (-9,4), substitute x=-9 and y=4 in the general form and solve for b.

\n" ); document.write( "(b) Every line perpendicular to the given line has an equation of the general form y = (-5/6)x+b.

\n" ); document.write( "To find the equation of the line perpendicular to the given line through (-9,4), substitute x=-9 and y=4 in the general form and solve for b.
