The scatterplot and regression line below show the average income, in dollars, in several major American cities plotted against
the rent for a 222-bedroom apartment in those cities.
The fitted line has a slope of 0.0310.0310, point, 031.
What is the best interpretation of this slope?

A
On average, each \$1$1dollar sign, 1 increase in average income was associated with a \$0.031$0.031dollar sign, 0, point, 031 increase in average rent.
(Choice B)
B
On average, each \$0.031$0.031dollar sign, 0, point, 031 increase in average income was associated with a 111 point increase in average rent.
(Choice C)
C
We would predict a city whose average income was \$0$0dollar sign, 0 to have an average rent of \$0.031$0.031dollar sign, 0, point, 031.
(Choice D)

We would predict a city whose average income was \$0$0dollar sign, 0 to have an average rent of \$0$0dollar sign, 0.
A graph plots Rent, in dollars per month, from 0 to 2000, in increments of 100, versus Average income, in dollars per year, from 0 to 50000, in increments of 5000, on an x y plane.14 points rise diagonally in a loose cluster between (36000, 825) and (58000, 1800). A regression line rises diagonally through the center of the cluster from (10000, 0) to (60000, 1520). All values estimated.
