2. If the slope of a line is 2 and it passes through the point (1, 4), write the equation of the line in slope-intercept form.

• y = 2x - 1

• y = 2x + 2

• y = x + 2

• y = 2x + 4

3. A bike rental shop charges a flat fee of $10 plus $2 for each hour rented. Write a linear equation to represent the total cost (C) in terms of hours rented (h). What is the slope in this context?

• C = 10 + 2h; slope = 2

• C = 5 + 2h; slope = 2

• C = 10 + 3h; slope = 3

• C = 10 + h; slope = 1

4. A student scores 80 on their first test and 90 on their second test. If the scores are plotted on a graph, what is the slope of the line connecting these two points?

• 20

• 10

• 5

• 15

5. A gardener plants flowers in a straight line. If the first flower is planted at (0, 1) and the second at (4, 5), what is the slope of the line? What does this slope represent in the context of the garden?

• 2

• 1

• 0.5

• -1

• y = 2x + 1

• y = 4x - 1

• y = x + 5

• y = 3x + 2

10. A runner completes a 5K race, finishing at (10, 15) minutes. If the runner started at (0, 0) minutes, what is the slope of the line representing their pace? What does this slope indicate about their speed?
