Misael Harmon · Answer 1

Answer: w=2r

Step-by-step explanation:

so let say the amount of water is y instead of w and the cup of rice is x instead of r.

so if we were to create a table we use the numbers given

x y

1 2 so as the cup of rice increase by 1 cup the amount of water increase

2 4 by two.

3 6 so we know the slope is 2/1 so the equation is w=2r
