2 x + 1 y = 7
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "
\n" ); document.write( "1 y = -2 x + 7
\n" ); document.write( "Divide by 1
\n" ); document.write( " y = -2 x + 7
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = -2.00
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal 0.5
\n" ); document.write( "m1*m2=-1
\n" ); document.write( "The slope of the required line will be 1/2
\n" ); document.write( "
\n" ); document.write( "m= 1/2 ,point ( 5 , 6 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "6 = 5/2 + b
\n" ); document.write( "b= 7/2
\n" ); document.write( "m= 1/2
\n" ); document.write( "The required equation is y = 1/ 2 x + 7/ 2
