Y = (m-1) x + 2m + 1, if the primary function is also a positive proportional function, the value of M is obtained
First order function: y = KX + B
Positive scale function: y = kx
So, 2m + 1 = 0
m=-1/2
Yes, because K is not equal to 0
So M-1 is not equal to 0
M is not equal to 1
To sum up, M = - 1 / 2
