6 x + 2 y = -6
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "
\n" ); document.write( "2 y = -6 x -6
\n" ); document.write( "Divide by 2
\n" ); document.write( " y = -3 x + -3
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = -3
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal 0.33
\n" ); document.write( "m1*m2=-1
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "m= 1/3 ,point ( 4 , -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 = 4/3 + b
\n" ); document.write( "b= -49/3
\n" ); document.write( "m= 1/3
\n" ); document.write( "The required equation isy = 1/ 3 x -49/ 3
