Linear or nonlinear
Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.
Problem types
- from the equation: y = 3x − 2, or y = x² + 1
- from a table: x = 0, 1, 2, 3 with y = 1, 4, 7, 10
- from a table with uneven x steps: x = 0, 1, 3, 6 with y = 3, 5, 7, 9
Sample Sheet · Level 1
- y = 9x
- y = x²
- y = x² + 6
- y = 2x + 3
- y = −5x − 7
- y = 2x
- y = 4x
- y = 6x
