Since the amount of water is directly proportional to the number of cups of rice, we can express this relationship using the equation y = kx, where y represents the amount of water and x represents the number of cups of rice.
Using the given coordinate (1/2, 1), we can substitute the values into the equation and solve for the constant of proportionality, k:
1 = k * 1/2
1 = k/2
k = 2
Now that we know k = 2, we can choose another value for x and find the corresponding value for y. Let's choose x = 4 for example:
y = 2x
y = 2 * 4
y = 8
Therefore, another point on the graph is (4, 8), where 4 represents the number of cups of rice and 8 represents the corresponding amount of water.
The amount of water is directly proportional to the number of cups of rice. The coordinates (1/2, 1) is on the graph of this proportional relationship. Identify another point on the graph.
