Question

Each of the options below describes a relationship that you need to graph on a coordinate plane. Which of the options will have a slope of 8? Select all that apply. A) Doing 4 pages of homework in 20 minutes B) Cycling 32 miles in 4 hours C) Buying 10 shirts for $80 D) Reading 72 pages in 9 hours

Answer 1

B ; C; D

Explanation:

The slope measures the rate of change in the dependent variable per unit change in the independent variable :

From the options :

Doing 4 pages of homework in 20 minutes :

The number of pages done per minute = slope

Slope = 20 / 4 = 5

To cycle 32 miles in 4 hours:.

Number of miles to cycle per hour to achieve the feat :

Slope = 32 /4 = 8

Buying 10 shirts for $80:

Cost per shirt = slope

Slope = $80 / 10

Slope = 8

Reading 72 pages in 9 hours

Number of pages read per hour :

72 / 9 = 8 pages
