Linear and Nonlinear Functions

Describe a Linear Function

Which of the following is a linear function?

A. y = 3x 3
B. y = (2x + 3)x
C. 5x = y – 3
D. y = 5x 2

Answer

Skill Practice! Determine whether each graph, equation, or table
represents a linear or nonlinear function. Explain.

1. 2. 3.

x 2
4. y = + 1 5. y = + 10 6. y = 8x
2 x

2
7. y = 6 8. 2x – y = 5 9. y = x + 4

2
10. y + 4x – 1 = 0 11. 2y – 8x + 11 = 0 12. y = 3x – 2

13. 14. 15.

x y x y x y
1 8 6 1 20 –4
2 5 12 3 15 –2
3 2 18 6 10 0
4 –1 24 10 5 2
