which of the following functions has a rate of change that stays the same?
A. y=1/3 x*2
B. y=2*x
C. y=-7x+9
D. y=x*2+1

B. y=2*x
clearly, the user meant * to mean exponent.
so the one with constant rate of change is C: -7x+9
so the one with constant rate of change is C: -7x+9
I apologize for the oversight. Yes, the function C: y=-7x+9 has a rate of change that stays constant at -7.
