If the intersection of the image of the first-order function y = KX + B and the inverse scale function y = KX is (2,3), then K=______ ,b=______ .

If the intersection of the image of the first-order function y = KX + B and the inverse scale function y = KX is (2,3), then K=______ ,b=______ .

Substituting (2,3) into y = KX to get k = 6, then substituting k = 6, (2,3) into y = KX + B to get b = - 9
