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.
| arrow_right_alt | scale factor is the x-value; perimeter is the y-value | |
| arrow_right_alt | scale factor is the x-value; area is the y-value | |
| arrow_right_alt | perimeter is the x-value; scale factor is the y-value | |
| arrow_right_alt | perimeter is the x-value; scale factor is the y-value |
