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?
A.
the increase in the number of pounds a boy gains each year
B.
the decrease in the number of pounds a boy gains each year
C.
the increase in the number of years for each pound a boy gains
D.
the decrease in the number of years for each pound a boy gains
The answer is A
1. The increase in the number of pouds a boy gains each year
2. 8.05
3. y= -0.18x + 10.06
4-6 Do yourself
7. 10%
8. The variables are gender and preferred method of learning. They are categorical variables.
9-10 do yourself
its a my dude
So I’m still confused what does that mean?
So what’s the answer plz help me
Yep Yep He right
To understand what the slope of the line of best fit means in this situation, let's break down the equation y = 1.73x + 80.13.
In this equation:
- "y" represents the weight of the boy at a given age (from 5 to 18).
- "x" represents the age of the boy.
The slope of the line, which is 1.73 in this case, tells us the rate of change between the age and weight variables. Specifically, it represents the increase in weight for every additional unit of age.
Therefore, the correct answer is A. The slope of 1.73 represents the increase in the number of pounds a boy gains each year.
Is it A, B, C, or D
the graph is weight vs age
so, what do you think?
what is the slope of a line?
