1 x -2 y = 3
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "
\n" ); document.write( "-2 y = -1 x + 3
\n" ); document.write( "Divide by -2
\n" ); document.write( " y = 0.50 x + -1.5
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 1/2
\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
\n" ); document.write( "
\n" ); document.write( "m= -2 ,point ( -2 , -5 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "-5 = 4.00 + b
\n" ); document.write( "b= -9
\n" ); document.write( "m= -2
\n" ); document.write( "The required equation is y =-2x-9
