The amount of water is directly proportional to the number of cups of rice. The coordinate (1/2, 1) on the graph of this proportional relationship. Identify another point on the graph.

Question

A. (1/4, 2)
B. (2, 6)
C. (3/2, 3)
D. (2/3, 4)

Answer 1

To identify another point on the graph, we can use the information given in the problem. Since the amount of water is directly proportional to the number of cups of rice, we can set up a proportion using the given coordinate of (1/2, 1).

This proportion can be written as:

(1/2) / 1 = x / y

Simplifying this proportion, we have:

1 / 2 = x / y

Cross multiplying, we get:

y = 2x

Now we can substitute the x-coordinate of the given coordinate (1/2, 1) into the equation to find the y-coordinate:

y = 2(1/2)
y = 1

Therefore, another point on the graph is (1/2, 1).

Hence, the correct answer is A. (1/4, 2).
