3 x + 1 y = 4
\n" ); document.write( "Find the slope of this line
\n" ); document.write( " y = -3 x + 4
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = -3
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal
\n" ); document.write( "m1*m2=-1
\n" ); document.write( "
\n" ); document.write( "m= 1/3 ,point ( 5 , 9 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "9 = 1/ 3*5 + b
\n" ); document.write( "b= 22/ 3
\n" ); document.write( "m= 1/3
\n" ); document.write( "The required equation is y = 1/ 3 x + 22/ 3
