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

• y-intercept

Each of the following representations shows a linear relationship between x and y. Which of the following representations have a rate of change of -2/3? Select THREE correct answers.

• Graph 2

• Table 2: x = -6, 0, 6, 9; y = 3, -1, -5, -7

• Table 1: x = -3, 0, 3, 6; y = 7, 9, 11, 13

• y = 3x - 2/3

• y = 5 - (2/3)(x - 1)
