Interpreting Intercepts of Linear Functions

How long had the rider been traveling when they were 10 kilometers away from home?

• 8 hours

• 2 hours

• 4 hours

• 6 hours

What was the distance from home after 4 hours of riding?

• 0 kilometers

• 10 kilometers

• 15 kilometers

• 5 kilometers

How much does the distance decrease every 2 hours?

• 10 kilometers

• 5 kilometers

• 15 kilometers

• 2 kilometers

What is the total time taken to reach home from the start?

• 8 hours

• 6 hours

• 10 hours

• 4 hours

How far was the rider initially from home when they started?

• 20 kilometers

• 15 kilometers

• 10 kilometers

• 5 kilometers

At what time does the distance from home become zero?

• 2 hours

• 4 hours

• 6 hours

• 8 hours

What is the slope of the distance-time graph?

• -2.5

• -7.5

• -10

• -5

What does the slope of the line represent in the context of this journey?

• Speed increase

• Rate of distance decrease

• Distance increase

• Time increase

What is the equation of the line representing the distance as a function of time?

• Distance = 20 - 5/2 * time

• Distance = 15 - 5/2 * time

• Distance = 10 - 5/2 * time

• Distance = 15 + 5/2 * time

Why is it useful to graph the distance against time?

• To calculate the exact time of travel

• To visualize the rate of distance change

• To determine the best route

• To predict weather conditions
