Question

The odometer in the car measures the number of miles driven by the car since it was made. During a trip, the odometer reading in Anita’s car is modeled by the function y=9500+55x where x represents the number of hours driven during the trip and y represents the odometer reading in miles. What was the odometer reading, in miles before Anita’s trip?

Answer 1

From question, we were told that the Odometer reading in Anita's car is modelled by the function:

y = 9500 + 550x

Where:

x represents the number of the number of hours driven during the trip and y represents the odometer reading in miles.

We are asked to find the Odometer reading in miles before Anita's trip.

The function given is in the slope intercept form.

So the Odometer reading before Anita's trip is the Y intercept of the function.

And the y intercept is 9500.

Therefore, the Odometer reading in miles before Anita's trip is 9500 miles.
