what you would have to do is find the slope of the linecontaining the points (5,-8) and (2,4).
so that would be:
m = ( y 2 y 1 ) ÷ ( x 2 x 1 ) = ( 4 ( 8 ) ) / ( 2 5 ) = 4
since it is parallel to the given equation of the line, thenthey would have the same slope.
k= -4 and your equation would be:
21y-4x= 4
