-0.2 x + 1 y = 7
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "
\n" ); document.write( "1 y = 0.2 x + 7
\n" ); document.write( "Divide by 1
\n" ); document.write( " y = 0.200 x + 7
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 0.20
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal -5
\n" ); document.write( "m1*m2=-1
\n" ); document.write( "The slope of the required line will be -5.00
\n" ); document.write( "
\n" ); document.write( "m= -5 ,point ( 4 , -3 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "-3 = -20.00 + b
\n" ); document.write( "b= 17
\n" ); document.write( "m= -5
\n" ); document.write( "The required equation is y = -5 x + 17
