The image of positive scale function passes through (- 2, - 3), and the analytic expression of this function is

The image of positive scale function passes through (- 2, - 3), and the analytic expression of this function is

Let the analytic expression of this function be y = KX, then
When x = - 2, y = - 3
-2k=-3
∴k=3/2
The analytic expression of this function is y = 3 / 2x
