It is known that the inverse scale function image y = K / X and the first-order function y = x + B Intersection a (1, - K + 4), B (n, - 1) Function expression and the value of n

It is known that the inverse scale function image y = K / X and the first-order function y = x + B Intersection a (1, - K + 4), B (n, - 1) Function expression and the value of n

y=2/x y=x+1 n=-2
