If we know that the positive scale function y = - 4x and the inverse scale function y = K / X intersect two points a and B, and the coordinate of a is (X.4), then the coordinate of point B is. Is there a (M + 3, n) B (m, n) ab symmetrical about the axis of symmetry? I don't know how to explain it
Substituting point a (x, 4) into the positive proportion function, we get 4 = - 4x, so x = - 1, point a is (- 1,4). This point satisfies the inverse proportion function, so substituting (- 1,4) into the inverse proportion function, 4 = K / (- 1), so k = - 4, the inverse proportion function is y = - 4 / X
By solving y = - 4x and y = - 4 / x, the point B is (1, - 4)
What do you mean by the axis of symmetry
