We know that y is a positive proportional function of X, and when x = 3, y = - 6; find its analytic formula; if point a (m, M + 3) is a point on its image, find the value of M

In general, the relation between two variables X and y can be expressed as a function of y = KX (k is a constant, and K ≠ 0), then y is called the positive proportion function of X. The positive proportion function belongs to the first-order function, which is a special form of the first-order function. In the first-order function y = KX + B, if B = 0, that is, the so-called "intercept on the Y axis" is zero, then it is
