Answer: This is a negative graph and it is proportional because it goes through the origin.
Step-by-step explanation:
Just beacause it goes through the origin does not mean it will be positive nor negative, if the line goes from the top left of the grid slanted down, it is negative. If the line goes from the top right of the graph slanted down, it is positive. It is proportional because it is a straight line that goes through the origin.
