The predicted number of grocery stores for a city with 485 thousand people can be found by plugging x=485 into the equation y= 0.159x + 3.824.
y = 0.159(485) + 3.824
y = 77.115 + 3.824
y = 80.939
Rounding to the nearest integer, the predicted number of grocery stores for a city with 485 thousand people is 81 grocery stores.
y = 0.159(485) + 3.824
y = 77.115 + 3.824
y = 80.939
Rounding to the nearest integer, the predicted number of grocery stores for a city with 485 thousand people is 81 grocery stores.
