How to Interpret a Graph

The video tutorial demonstrates how to interpret a graph modeling the linear relationship between distance and time. It covers four parts: identifying what a specific point on the graph represents, calculating the average speed of a car, estimating the average speed of a second car, and estimating the total distance traveled by a third car. The tutorial uses real-world examples and mathematical calculations to explain concepts like ordered pairs, unit rates, and proportional relationships.

What does the point (6, 300) represent on the graph?

• The car traveled 30 miles in 6 hours.

• The car traveled 6 miles in 30 hours.

• The car traveled 300 miles in 6 hours.

• The car traveled 6 miles in 300 hours.

How do you determine the average speed of the car from the graph?

• By finding the slope of the line.

• By adding the x and y coordinates of the points.

• By measuring the length of the line.

• By counting the number of points on the graph.

What is the average speed of the car if it travels 300 miles in 6 hours?

• 40 mph

• 60 mph

• 50 mph

• 30 mph

How would you estimate the average speed of a car that travels 209 miles in 5 hours and 6 minutes?

• By dividing 200 by 5

• By dividing 209 by 5.1

• By dividing 209 by 5

• By dividing 210 by 5

What is the estimated average speed of the second car?

• 60 mph

• 40 mph

• 30 mph

• 50 mph

How do you estimate the total distance traveled by a car moving at 61 mph for 8 hours and 28 minutes?

• Multiply 61 by 8 and add 30

• Multiply 60 by 8 and add 30

• Multiply 61 by 8.5

• Multiply 60 by 8.5

What is the estimated total distance traveled by the third car?

• 520 miles

• 510 miles

• 500 miles

• 480 miles
