Question

the graph shows the weight of a pitcher, y, as a function of the number of cups of water in the pitcher, x. the initial value is 12. it represents the weight in ounces of the empty pitcher. is the rate of change positive or negative? the line slants? from left to right. that means the rate of change is?

Explanation:

Step1: Observe the graph's slope

As the number of cups of water (x - variable) increases from left - to - right, the weight of the pitcher (y - variable) increases.

Step2: Determine rate of change sign

Since y increases as x increases, the rate of change is positive.

Answer:

The line slants upward from left to right. That means the rate of change is positive.
