5 x -9 y = 4
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "make y the subject
\n" ); document.write( "-9y=-5x+4
\n" ); document.write( "Divide by -9
\n" ); document.write( " y = (5/ 9)x- 4/9
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m = 5/ 9
\n" ); document.write( "The slope of a line parallel to the above line will be the same
\n" ); document.write( "The slope of the required line will be 5/ 9
\n" ); document.write( "m= 5/ 9 ,point ( 9 , -8 )
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "-8 = 5 + b
\n" ); document.write( "b= -14
\n" ); document.write( "m= 5/9
\n" ); document.write( "Plug value of the slope and b in y = mx +b
\n" ); document.write( "The required equation is y = 5/9 x-14
\n" ); document.write( "
