\n" ); document.write( "Find an equation of the line satisfying the given conditions.
\n" ); document.write( "Through(-3,9),perpendicular to 2x+3y=21
\n" ); document.write( "

2x + 3y = 21 
\n" );
document.write( "3x + 2y = c -------- Switching coefficients on variables, and changing the constant to c
\n" );
document.write( "3x - 2y = c -------- NEGATING coefficient on y
\n" );
document.write( "3x - 2y = 3(- 3) - 2(9) -------- Substituting GIVEN point (- 3, 9) to determine c
\n" );
document.write( "3x - 2y = - 9 - 18
\n" );
document.write( " ---- Required equation \n" );
document.write( "

\n" );
