1 y = -1 1/ 3 x + 5
\n" ); document.write( "Divide by 1
\n" ); document.write( " y = -4/ 3 x + 5
\n" ); document.write( "Compare this equation with y=mx+b, m= slope & b= y intercept
\n" ); document.write( "slope m = -4/3
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal 3/4
\n" ); document.write( "m1*m2=-1
\n" ); document.write( "The slope of the required line will be 3/4
\n" ); document.write( "
\n" ); document.write( "m= 3/4 ,point ( 5 , -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 = 15/4 + b
\n" ); document.write( "b= -31/4
\n" ); document.write( "m= 3/4
\n" ); document.write( "The required equation isy = 3/ 4x- 31/ 4
