document.write( "a. Passing through the point(4,9)and perpendicular to the line 4x+7y=12
\n" );
document.write( "perpendicular to the line with the equation 
\n" );
document.write( "4x + 7y = 12  OR y = (-4/7)x + 12/7    m = (-4/7)
\n" );
document.write( "Perpendicular lines have slopes that are negative reciprocals on one another
\n" );

document.write( " y = (7/4)x + b  |Using ordered pair (4,9) to solve for b
\n" );
document.write( " 9 = (7/4)*4 + b
\n" );
document.write( " 2 = b
\n" );
document.write( " y = (7/4)x + 2   OR  7x + 4y = 8\r
