De'Mario was solving translation of a linear of f(x) = x and g(x) = x - 2, but after he was done he noticed their graphs where different from his teacher. His graph is on the left.

(Of the blue Line)

What did he do wrong?

• De'Mario did not put it right on the y - axis.

• De'Mario didn't read the slope correctly.

• De'Mario is right the teacher is just wrong.
