1 y = 5 x + 9
\n" ); document.write( "Divide by 1
\n" ); document.write( " y = 5 x + 9
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 5.00
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal -0.2
\n" ); document.write( "m1*m2=-1
\n" ); document.write( "The slope of the required line will be - 1/5
\n" ); document.write( "
\n" ); document.write( "m= - 1/5 ,point ( 0 , 6 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "6 = 0.00 + b
\n" ); document.write( "b= 6
\n" ); document.write( "m= - 1/5
\n" ); document.write( "The required equation is y = - 1/ 5 x + 6
