EXAMPLE 1 Algebra 2 Section 1.3 Notes Example 1: The graph shows the distance Asteroid 2012 DA14 travels in x seconds. Write an equation of the line and interpret the slope. The asteroid came within 17,200 miles of Earth in February About how long does it take the asteroid to travel that distance?

EXAMPLE 2 Example 2: The graph shows the distance Allison hikes in x hours. Write an equation of the line and interpret the slope. How long does it take Allison to hike 14 miles traveling at the same rate?

EXAMPLE 3 The graph shows the remaining balance y on a car loan after making x monthly payments. Write an equation of the line and interpret the slope and the y-intercept. What is the remaining balance after 36 payments?

EXAMPLE 4 Two prom venues charge a rental fee plus a fee per student. The table shows total costs for different numbers of students at Lakeside Inn. The total cost y (in dollars) for x students at Sunview Resort is represented by the equation. Which venue charges less per student? How many students must attend the prom for the costs to be the same?

EXAMPLE 5 Kelly and Kim are both babysitters. Kelly charges a flat fee of $10 plus $6 per hour to babysit. The table shows the total hourly fee that Kim charges to babysit. Who charges more per hour? How many hours must Kim and Kelly babysit for their total fees to be the same?
