4 x + 3 y = 6
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "
\n" ); document.write( "3 y = -4 x + 6
\n" ); document.write( "Divide by 3
\n" ); document.write( " y = -1.333 x + 2
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = -1.33
\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( "The slope of the required line will be 0.75
\n" ); document.write( "
\n" ); document.write( "m= 3/4 ,point ( 4 , 2 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "2 = 3.00 + b
\n" ); document.write( "b= -1
\n" ); document.write( "m= 3/4
\n" ); document.write( "The required equation is y = 3/ 4 x-1
