Calculate the slope of the line in the figure below:

The slope of the line is:

A.
B.
C.
D.
Correct! The slope of the line in the figure is -0.5
Sorry, the slope of the line is -0.5! Remember that slope is defined as the vertical distance traveled (the “rise”) divided by the horizontal distance traveled (the “run”).

Calculate the slope of the line in the figure below:

The slope of the line is:

A.
B.
C.
D.
Correct! The slope of the line in the figure is 0.5
Sorry, the slope of the line is 0.5! Remember that slope is defined as the vertical distance traveled (the “rise”) divided by the horizontal distance traveled (the “run”). In the figure the rise from point A to B is 2 and the run is 4. This makese the slope 2/4 = 0.5.

2.

Calculate the slope of the line in the figure below:

The slope of the line is:

A.
B.
C.
D.
Correct! The slope of the line in the figure is -1.25
Sorry, the slope of the line is -1.25! Remember that slope is defined as the vertical distance traveled (the “rise”) divided by the horizontal distance traveled (the “run”). In the figure the rise from point A to B is -25 and the run is 20. This makese the slope -25/20 = -1.25.

3.

Calculate the slope of the line in the figure below:

The slope of the line is:

A.
B.
C.
D.
Correct! The slope of the line in the figure is 4
Sorry, the slope of the line is 4! Remember that slope is defined as the vertical distance traveled (the “rise”) divided by the horizontal distance traveled (the “run”). In the figure the rise from point A to B is 8 and the run is 2. This makese the slope 8/2 = 4.

4.

Calculate the slope of the line in the figure below:

The slope of the line is:

A.
B.
C.
D.
Correct! The slope of the line in the figure is 1/10 or 0.1
Sorry, the slope of the line is 1/10 or 0.1! Remember that slope is defined as the vertical distance traveled (the “rise”) divided by the horizontal distance traveled (the “run”). In the figure the rise from point A to B is 10 and the run is 100. This makes the slope 10/100 = 1/10 = 0.1.

5.

Calculate the slope of the line in the figure below:

The slope of the line is:

A.
B.
C.
D.
Correct! The slope of the line in the figure is -0.16.
Sorry, the slope of the line is -0.16! Remember that slope is defined as the vertical distance traveled (the “rise”) divided by the horizontal distance traveled (the “run”). In the figure the rise from point A to B is -40 and the run is 250. This makes the slope -40/250 = -0.16.
