Looking for linear equations & functions worksheets for Grade 8? This page has 1,994+ TEKS-aligned practice questions on this exact topic. Every question goes through an AI quality gate before publishing — no typos, no wrong answer keys, no factually-broken explanations.
Below: a sample of 8 questions with answers and explanations so you can see what's on the worksheet before you print. Each question has the correct choice marked and a one-line "why" so kids who get it wrong understand the fix.
Solve for x: 4x + 18 = 3x + 28
- 11
- 12
- 9
- 10 ✓
Why: Subtract 3x from both sides: 1x + 18 = 28. Then 1x = 10. Divide by 1: x = 10.
Solve for x: 3x − 10 = 8x + 45
- -12
- -9
- -10
- -11 ✓
Why: Subtract 8x from both sides: -5x − 10 = 45. Then -5x = 55. Divide by -5: x = -11.
Solve for x: 9x + 3 = 1x + 67
- 7
- 9
- 8 ✓
- 10
Why: Subtract 1x from both sides: 8x + 3 = 67. Then 8x = 64. Divide by 8: x = 8.
Solve for x: 4x + 5 = 1x + 11
- 4
- 2 ✓
- 3
- 1
Why: Subtract 1x from both sides: 3x + 5 = 11. Then 3x = 6. Divide by 3: x = 2.
Does the set { (6, 8), (1, -9), (-5, -9), (6, -2) } represent a function?
- Yes
- No ✓
- Cannot tell
Why: Two ordered pairs share the same x-value but different y-values, so this is NOT a function.
Does the set { (-6, 1), (2, 8), (-1, 4), (-6, -5) } represent a function?
- Yes
- Cannot tell
- No ✓
Why: Two ordered pairs share the same x-value but different y-values, so this is NOT a function.
Does the set { (6, -5), (4, -4), (1, -10), (5, 8) } represent a function?
- Yes ✓
- No
- Cannot tell
Why: Each x-value is paired with exactly one y-value, so this IS a function.
Does the set { (1, -2), (-1, 3), (4, -3), (-5, 2) } represent a function?
- Cannot tell
- Yes ✓
- No
Why: Each x-value is paired with exactly one y-value, so this IS a function.
