Question

isaac enjoys his work at a vet clinic, especially when a kitten comes in. he made a scatter plot to show the relationship between the ages in months, x, and weights in pounds, y, of the last several kittens that visited the clinic. then, he drew a line of best fit.
the equation for the line of best fit is y = 1.1x - 0.2.
in this context, what is the meaning of 1.1?
the average age of the kittens that visited the clinic was 1.1 months.
on average, the kittens that visited the clinic gained 1.1 pounds per month.
on average, the kittens that visited the clinic gained a pound every 1.1 months.
the average weight of the kittens that visited the clinic was 1.1 pounds.

Explanation:

The line of best fit is in the form \(y = mx + b\), where \(m\) is the slope. Here, \(m = 1.1\), representing the rate of change of weight (\(y\)) with respect to age (\(x\)). So 1.1 means the average weight gain per month.

Answer:

On average, the kittens that visited the clinic gained 1.1 pounds per month.
