A biologist tracks the lengths and weights of a group of mice, and the results are graphed on the coordinate grid. Which best describes the relationship between the lengths and weights of the group of mice?

On average, a
1.0
cm increase in length is associated with a
0.75
g increase in weight.
On average, a 1 point 0 cm increase in length is associated with a 0 point 7 5 g increase in weight.

On average, a
1.0
cm increase in length is associated with a
