A mechanic performs oil changes on automobiles. The table shows the linear relationship between the number of oil changes completed after different amounts of time. | Number of Hours | Number of Oil Changes | |-----------------|-----------------------| | 1.5 | 4.5 | | 3 | 9 | | 5.5 | 16.5 | | 8 | 24 | Choose the correct answer from each drop-down box to complete the sentence. The mechanic completes [3, 4.5] oil changes per hour, which represents the [rate of change, y-intercept] of the linear function.

• 3

• 4.5

• rate of change
