Doug believes that the function y = 6 is linear, while Olga believes that it is not linear. Who is right, and why?

• Doug is right because the function cannot be written in the form y = mx + b.

• Doug is right because the function can be written in the form y = mx + b, with m = 0

• Olga is right because the function cannot be written in the form y = mx + b.

• Olga is right because the function can be written in the form y = mx + b, with m = 0.
