For example, the following solution 1. Let the analytic expression of a function be y = KX + B, Because the function image passes through the points a (- 1,3) and B (2, - 3), the value of the two coordinate points is substituted into the analytic formula of the function to obtain k = - 2, B = 1, that is, the analytic formula is y = - 2x + 1
