3. A bike rental service charges a flat fee of $10 plus $2 for every hour rented. If you graph the total cost against the number of hours, what is the slope of the line?

• 5

• 0

• 10

• 2

4. A student plots the number of hours studied against the score received on a test. If the graph shows a line that rises 5 points for every 1 hour studied, what does the slope represent in this context?

• The slope represents the maximum score achievable.

• The slope shows the average score of all students.

• The slope indicates the total hours studied.

• The slope represents the increase in test score per hour studied.
