Question 1 (1 point) Saved

Which of the following data sets is best described by a linear model?
{(5, 1), (4,0), (3, 1), (2, 4)}
{(5, 1), (4, 2), (3, 4), (2,8)}
{(5,1),(4, -1), (3,-3), (2,-5)
{(5, 12), (4, 6), (3, 3), (2, 1.5)}

Answer 1

`\huge\boxed{\text{The third data set}}`

A linear model can describe a data set in this way: When the data set is graphed, the points go in a straight line.

Attached are graphs of each data set, colored red, blue, green, and orange (in that order).

As you can see, the third data set can be represented with a straight line, while the others cannot.
