1 y = 3 x -3
\n" ); document.write( "Divide by 1
\n" ); document.write( " y = 3 x + -3
\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( "
\n" ); document.write( "m= - 1/3 ,point ( 10 , -3 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "-3 = -3.33 + b
\n" ); document.write( "b= 0.33
\n" ); document.write( "m= - 1/3
\n" ); document.write( "The required equation isy = - 1/ 3 x + 1/ 3
