B. It increases at a constant rate.
C. It decrases at a constant rate.
D. It has an input of -2 with a corresponding output of 6.

Answer:

-2x + y = -1

or y = 2 x - 1

Since y = m x + b is a straight line it is linear with m = 2

Thus it must increase at a constant rate  is the only true statement
