Is the volume of water increasing or decreasing here? what is its rate of increase or decrease in liters per hour? coordinate plane with x-axis labeled number of hours and y-axis labeled volume in liters. graph of a line contains the following points: (1, 2) and (3, 1.5)

The volume is decreasing here .

The rate of change = -0.25

Step-by-step explanation:

Given: In a graph , coordinate plane with x-axis labeled Number of Hours and y-axis labeled Volume in Liters.

The graph of a line contains the points: (1, 2) and (3, 1.5)

From the points, change in volume = change in y

⇒ Change in volume =

Change in time = change in x

⇒ Change in hours=

The rate of change for a graph is given by:-

Since, the rate of change is negative , therefore, the volume of water decreases.

for the points! : )

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
