The line segment's slope represents the period during which the speed decreases is b. The slope is -10.

What is the line segment's slope?

The slope of a line segment measures the steepness of the line segment.

The slope is the ratio of the rise (the change in vertical height, y, between the endpoints) over the run (the difference in horizontal length, x, between the endpoints.

Data and Calculations:

Elapsed Time (sec)     Speed (mph)

1                                        45

2                                       35

3                                       25

4                                       15

5                                       15

6                                       15

The Slope of the line segment during speed decreases = y₂ - y₁ ÷ x₂ - x₁.

= (35 - 45) / (2 - 1)

= -10/1

= -10

Thus, b. The slope is -10.
