A triangle has an area of 6 square inches and a perimeter of 12 inches. Suppose it is dilated by some scale factor, and the area and perimeter of the image are calculated.
Match each graph with the relationship it represents.

scale factor is the x-value; perimeter is the y-value
scale factor is the x-value; area is the y-value
perimeter is the x-value; scale factor is the y-value
