-6 x + 8 y = 3
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "
\n" ); document.write( "8 y = 6 x + 3
\n" ); document.write( "Divide by 8
\n" ); document.write( " y = 3/4 x + 0.38
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 3/4
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal -4/3
\n" ); document.write( "m1*m2=-1
\n" ); document.write( "The slope of the required line will be -1 1/3
\n" ); document.write( "
\n" ); document.write( "m= -4/3 ,point ( -3 , -15 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "-15 = 4.00 + b
\n" ); document.write( "b= -19
\n" ); document.write( "m= -4/3
\n" ); document.write( "The required equation is,y =-4/ 3 x -19
