Linear Relationships Review

1. Which equation best represents the relationship between numbers in the ordered pairs: (1, -2), (2, 4), (3,10), (4, 16) y = x - 3 y = 4x y = 5x - 4 y = 6x - 8 2. Which expression describes a function which includes all of the ordered pairs: (3, 6), (9, 4), (15, 2) y = 3x - 7 y = -3x + 7 y = -1 +7 y = -1 -7 3. Elijah paid $80, plus $0.08 per mile, to rent a car for one week. If x represents the number of miles he drives, which linear equation could Elijah use to determine y, the total cost of renting the car? y = 88x y = x + 80.08 y = 80x + 0.08 y = 0.08x + 80 4. Look at the equation shown: 5x + 2 = 12x - 3 Solve for X. Write your answer in the space below. X = ? 5. In order for this equation to be true, what value must x have? 8x + 4 = 14x - 6 - 5 - 1 4 10
