Question

A medical student is conducting a study to track boys’ weight from age 5 to age 18. The student graphs some data and determines the line of best fit is y = 1.73x + 80.13. What does the slope mean in this situation

Answer 1

The slope means : A.

the increase in the number of pounds a boy gains each year

Explanation:

Given the equation for line of best fit as : y=1.73x +80.13

At the age of 5 the weight will be;

x=5, y= 1.73*5+80.13 =88.75 pounds

At the age of 6, the weight will be;

x=6, y=1.73*6+80.13 = 90.15

Difference in weight after one year increase of age will be;

90.15-88.75=1.73

This means after a year, a boy gains 1.73 pounds
