If Y-1 is proportional to 2-x, then the following statement is correct () A. Y is a linear function of X B. Y is a linear function of X C. It's a function of X, but it's not a positive scale function D. Y is not a function of X Is y a linear function of X? Why? y=-kx+2k+1 So if y is a function of X, is it a linear function? B is a positive proportional function

Y-1 is proportional to 2-x
Let Y-1 = K (2-x)
y=2k-kx+1
y=-kx+2k+1
So y is a function of X,
And when k = - 1 / 2,
Y = x / 2, is a positive proportional function
So C is not correct
So choose a
