3 y = 1 x -4
\n" ); document.write( "Divide by 3
\n" ); document.write( " y = 1/ 3 x + -1 1/3
\n" ); document.write( "Compare this equation with y=mx+b, m= slope & b= y intercept
\n" ); document.write( "slope m = 1/3
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal -3
\n" ); document.write( "Because m1*m2 =-1
\n" ); document.write( "The slope of the required line will be -3
\n" ); document.write( "
\n" ); document.write( "m= -3 ,point ( -2 , 1 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "1 = 6 + b
\n" ); document.write( "b= -5
\n" ); document.write( "m= -3
\n" ); document.write( "The required equation is y = -3 x -5
