Rhonda kept track of the cats at a shelter where she volunteers. She measured how many times per day each cat ate, and she also ranked their activity level on a scale from 1 to 10 each day. She found the line of best fit for the data has
the equation y = 0.23x + 4.1, where x represents the activity level and y represents the number of meals eaten.
If a cat had an activity level of about 9, approximately how many meals is it likely to have eaten?
