Answer:
2 cookies per dollar
Step-by-step explanation:
You can take any point on the line, turn it into a fraction and simplify.
For example: 4 cookies cost $2.
4 cookies per 2 dollar is 2 cookies per 1 dollar (divide by 2)
If you take another point, e.g., 14 cookies for 7 dollar, you'll be dividing by 7 to simplify and get the same answer.
