1. The equation y = 3x + 5 represents the cost (y) of a taxi ride for 'x' miles. What does the slope of this equation represent in the context of the taxi ride?
2. A linear function models the amount of water in a tank over time. If the slope is -10 gallons/minute, what does this tell you about the water in the tank?
3. In the equation y = 3x + 5 from Question 1, what does the y-intercept represent in the context of the taxi ride?
4. A plant's height (in cm) over time (in weeks) is modeled by a linear equation. If the y-intercept is 15 cm, what does this indicate about the plant?
5. The graph below shows the distance (y) a car travels over time (x). What is the most appropriate interpretation of the slope of this line?
The initial distance of the car.
The speed of the car.
The total time traveled.
The maximum distance traveled.
6. For the same graph in Question 5, what does the y-intercept represent?
The car's final destination.
The time it takes to travel one mile.
The initial distance from the starting point.
The total distance covered.
7. A linear model for the temperature of a cooling cup of coffee is T = -2t + 90, where T is the temperature in Celsius and t is the time in minutes. The slope indicates that the coffee's temperature by 2 degrees Celsius every .
8. In the equation C = 2.50 + 0.75n, representing the cost (C) of renting a bike for 'n' hours, the y-intercept of 2.50 represents the , while the slope of 0.75 represents the .
9. If the slope of a line is positive, it means that as the x-value increases, the y-value decreases.
True
False
10. The y-intercept always represents the starting value or initial condition in a real-world problem.
True
False
