what an equation of the line contain the given point and perpendicular to the given line (8,7) 4x+5=9
\n" ); document.write( "-------------
\n" ); document.write( "4x + 5 = 9
\n" ); document.write( "4x = 4
\n" ); document.write( "x = 1
\n" ); document.write( "That's parallel to the y-axis
\n" ); document.write( "Perpendicular is parallel to the x-axis
\n" ); document.write( "--> y = 7
\n" ); document.write( "
\n" );
