It is known that the image of the first-order function is parallel to the image of the positive scale function y = - 2 / 3x and passes through the point m (0,4) If the points (- 8, m) and (n, 5) are on the image of a linear function, try to find the values of M and n

It is known that the image of the first-order function is parallel to the image of the positive scale function y = - 2 / 3x and passes through the point m (0,4) If the points (- 8, m) and (n, 5) are on the image of a linear function, try to find the values of M and n

Let the analytic expression of a function be y = KX + B
Parallel to the positive proportional function y = - 2 / 3x, we can get k = - 2,
Through the point m (0,4), we can get: B = 4
So there is: y = - 2 / 3x + 4
When the point (- 8, m) is on the straight line, the equation is as follows:
M = - 2 / 3x (- 8) + 4, i.e. M = 28 / 3
The point (n, 5) is on the straight line, which is substituted into the equation
5 = - 2 / 3N + 4, that is: n = - 3 / 2
