Two questions about function mathematics 1. It is known that the image of the first-order function y = 3x-2k intersects with the image of the inverse scale function y = K-3 of X. the ordinate of one of the intersections is 6. Find the coordinates of the intersection of the image of the first-order function and the x-axis and y-axis 2. The analytic expressions of the inverse scale function to the first-order function are determined respectively when the intersection of the image of the inverse scale function y = x / K and the first-order function y = MX + n is a (- 3,4) and the distance from the intersection of the image of the first-order function and the X axis to the origin is 5

Y 1 = 6 = (K-3) / x 1 = 3 (K-3) / (6 + 2K) K-3 = 2 (6 + 2K) = 12 + 4K, 3 K = - 15, k = - 5 the equation of first-order function is y = 3x + 10, it intersects with X axis: (- 10 / 3,0), the intersection of Y axis: (0,10) 2,4 = K / (- 3), k = - 12, the equation of inverse scale function is y = - 12 / X4 = - 3M +
