-3 x + 4 y = -8
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "
\n" ); document.write( "4 y = 3 x -8
\n" ); document.write( "Divide by 4
\n" ); document.write( " y = 3/ 4 x + -2
\n" ); document.write( "Compare this equation with y=mx+b, m= slope & b= y intercept
\n" ); document.write( "slope m = 3/4
\n" ); document.write( "
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal -4/3
\n" ); document.write( "Because m1*m2 =-1
\n" ); document.write( "The slope of the required line will be -4/3
\n" ); document.write( "
\n" ); document.write( "m= -4/3 ,point ( -12 , 7 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "7 = 16 + b
\n" ); document.write( "b= -9
\n" ); document.write( "m= -4/3
\n" ); document.write( "The required equation is y = -4/ 3 x -9
