Question

The equation of the linear regression line represents the relationship between the amount a person earns, x, and the amount saved, y.

yˆ=0.01x+50

What does the slope of the line represent?



For every $100 a person earns, the savings increases by 1 cent.

For every $100 a person earns, the savings increases by $1.

For every $100 that a person earns, the savings decreases by $1.

For every $1 a person earns, the savings increases by $100.

Answer 1

Answer: b

Explanation:

Answer 2

Option B is the correct option.

Explanation:

The equation of the linear regression line represents the relationship between the amount and a person's earning.

y = .01x + 50

Or
`y=(1)/(100)x+50`

It's in the form of y = mx + c

Where y = amount of saving

x = amount of saving

m = slope of the line = change in saving/change in earning

m = 1/100 = saving increase by $1 / earning increase of $100

Therefore slope represents for every $100 a person earns, the saving increases by $1.

Option B. is the answer.
