The answer should be D because:
A cannot be the right answer because when you plug 0 as x, the y value is 1 and not 3 and on the graph, the line crosses (0,3)
C cannot be correct because the -1.2 would result in negative answers and the graph was never in the negative sections of the graph
B cannot be correct because 0.2 is smaller than 1 therefore when you multiply by it, the graph should go down(lower) from the left to the right.
The only possible correct answer is D
