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

Question

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

Answer 1

To determine another point on the graph, we need to find the constant of proportionality.

Using the given information, we know that when the amount of water (x) is 1/2, the number of cups of rice (y) is 1.

So, the constant of proportionality is: k = y/x = 1/2 = 0.5.

To find another point, we can choose any value for x, and then find y using the constant of proportionality.

Let's choose option D. When x = 3/2, we get:

y = k * x = 0.5 * (3/2) = 1.5.

Therefore, the point (3/2, 1.5) is another point on the graph.

Therefore, the answer is D. (3/2, 3).
