To determine how many miles a car that is 16 years old is expected to have, we need to substitute x = 16 into the equation y = 12x + 5 and solve for y.
y = 12(16) + 5
y = 192 + 5
y = 197
Therefore, a car that is 16 years old is expected to have 197,000 miles.
The equation for the trend line of the scatterplot is y = 12x + 5, where x represents the car's age, and y represents the mileage (in thousands of miles). Using this equation, determine how many miles a car that is 16 years old is expected to have. Show your work.
