Lesson 2 Homework PracticeRepresenting Linear Functions
Find four solutions of each equation. Write the solutions as ordered pairs.1–6. Sample answers are given.
1. y = x - 5 2. y = -7 3. y = -3x + 1 (-1, -6), (0, -5), (-1, -7), (0, -7), (-1, 4), (0, 1),
(1, -4), (2, -3) (1, -7), (2, -7) (1, -2), (2, -5)
4. x - y = 6 5. y = 2x + 4 6. 7x - y = 14 (-1, -7), (0, -6), (-1, 2), (0, 4), (-1, -21), (0, -14),
(1, -5), (2, -4) (1, 6), (2, 8) (1, -7), (2, 0)
Graph each equation by plotting ordered pairs. 7. y = 2x - 1 8. 6x + y = 2 9. y = x + 4

13. Kirsten is making gingerbread cookies using her grandmother’s recipe and needs to convert grams to ounces. The equation y = 0.04x describes the approximate number of ounces y in x grams.
a. Find three solutions of this equation. Sample answer: (100, 4), (150, 6), (200, 8)
b. Draw the graph that contains these points.
c. Do negative values of x make sense in this case? Explain. No; a recipe cannot contain a negative number
of grams of an ingredient.x
