1 y = 0.5 x + 3
\n" ); document.write( "Divide by 1
\n" ); document.write( " y = 0.5 x + 3
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 0.5
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal -2
\n" ); document.write( "m1*m2=-1
\n" ); document.write( "The slope of the required line will be -2.00
\n" ); document.write( "
\n" ); document.write( "m= -2 ,point ( 3 , -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 = -6.00 + b
\n" ); document.write( "b= 2
\n" ); document.write( "m= -2
\n" ); document.write( "The required equation is y = -2 x + 2
