Question

The water level of a river was measured each day during a two-week period. The graph models the linear relationship between the water level of the river in feet and the number of days the water level was measured.

Water Level of River:

Day 1: 28 ft
Day 2: 24 ft
Day 3: 20 ft
Day 4: 16 ft

Answer 1

The water level of a river follows a linear relationship with the number of days it is measured.

Step-by-step explanation:

The subject of this question is Mathematics and the grade level is High School.

The question is asking about the linear relationship between the water level of a river and the number of days the water level was measured. To understand this relationship, we can look at the given data points:

Day 1: 28 ft

Day 2: 24 ft

Day 3: 20 ft

Day 4: 16 ft

From these data points, we can observe that the water level decreases by 4 ft each day.

Therefore, the relationship between the water level and the number of days can be represented by the equation:

water level = 32 - 4 * number of days.

For example, on Day 1, the water level is 28 ft, which can be calculated as:

32 - 4 * 1 = 28.

Similarly, on Day 2, the water level is 24 ft, which can be calculated as: 32 - 4 * 2 = 24.
