You can put this solution on YOUR website!
y = 3 x + 3
\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( "Because 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 ( 1 , 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 = - 1/ 3 + b
\n" ); document.write( "b= 4/3
\n" ); document.write( "m= - 1/3
\n" ); document.write( "The required equation is y = - 1/ 3 x + 4/ 3
