y = 3 x + 2
\n" ); document.write( "Compare this equation with y=mx+b, m= slope & b= y intercept
\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 - 1/3
\n" ); document.write( "m1*m2=-1
\n" ); document.write( "The slope of the required line will be - 1/3
\n" ); document.write( "
\n" ); document.write( "m= - 1/3 ,point ( -2 , 4 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "4 = 2/ 3 + b
\n" ); document.write( "b= 10/3
\n" ); document.write( "m= - 1/3
\n" ); document.write( "The required equation is y =- 1/ 3 x+10/ 3
