write equation y = -(1/2)x + 2/5 in Ax + By + C = 0 form

[NEHA]

Write the eqaution y = -(1/2)x + 2/5 in general form (meaning "Ax + By + C = 0") with integers as constants.

. . .(1/2)x + y - 2/5 = 0

. . .(10)(1/2)x + (10)y - (10)(2/5) = 0

. . .5x + 10y - 4 = 0

That's how I'd do it, but I am a little concerned about the sign on 'C'. How exactly is one required to emulate this "General Form"?
