It is known that the image of the first-order function y = MX + N and the inverse scale function y = (3N-M) / X intersects at the point (1 / 2,2), and the value of M, N and another intersection point are obtained

It is known that the image of the first-order function y = MX + N and the inverse scale function y = (3N-M) / X intersects at the point (1 / 2,2), and the value of M, N and another intersection point are obtained

Because the intersection point of two functions is (1 / 2,2), substituting x = 1 / 2. Y = 2 into two functions, we get the equations 2 = 1 / 2m + n; 2 = (3N-M) / (1 / 2), we get n = 1, M = 2, substituting the values of M and n into two functions, we get y = 2x + 1, y = 1 / x, y = 1 / x into y = 2x + 1, we get the solutions x = 1 / 2, x = - 1x = 1 / 2, that is, the intersection point (1 / 2,2) gets x = - 1
