Question

1. what type of relationship is shown by the graph below? variables: 1. as the slope of the land increases, the speed of water in a stream also increases. a. what type of relationship is this? b. what is the independent variable? c. what is the dependent variable? 2. as elevation up a mountain increases, the temperature decreases. a. what type of relationship is this? b. what is the independent variable? c. what is the dependent variable?

Explanation:

Step1: Analyze the first - relationship

When the slope of the land increases, the speed of water in a stream also increases. This is a direct relationship. The independent variable is the cause, which is the slope of the land. The dependent variable is the effect, which is the speed of water in the stream.

Step2: Analyze the second - relationship

When the elevation up a mountain increases, the temperature decreases. This is an inverse relationship. The independent variable is the elevation up a mountain, and the dependent variable is the temperature.

Step3: Analyze the graph

The graph shows that velocity remains constant over time. This is a constant relationship.

Answer:

1.
a. Direct relationship
b. Slope of the land
c. Speed of water in the stream
2.
a. Inverse relationship
b. Elevation up a mountain
c. Temperature

1. Constant relationship
