Question

Santiago buys a container of milk to make atole. The cups of milk left in the container, y, is a linear function of the number of batches he makes, 2. The graph of the function passes through the points (1, 12) and (3,4).
Find and describe the rate of change of the function.
The rate of change is
It represents
? container for each batch of atole made.

Answer 1

Slope m = (4 − 12)/(3 − 1) = −8/2 = −4.

The rate of change is −4 cups per batch. It means the amount of milk in the container decreases by 4 cups for each additional batch of atole made.
