Looking for linear functions worksheets for Algebra I? This page has 2,374+ 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.
What is the slope between the points (-9, 5) and (-10, -9)?
- 16
- 14 ✓
- 15
- 13
Why: m = (y₂ − y₁)/(x₂ − x₁) = (-14)/(-1) = 14.
Find the slope of the line through (-8, 3) and (-4, -13).
- -4 ✓
- -5
- -2
- -3
Why: m = (y₂ − y₁)/(x₂ − x₁) = (-16)/(4) = -4.
What is the slope between the points (-8, -7) and (-10, 7)?
- -6
- -7 ✓
- -5
- -8
Why: m = (y₂ − y₁)/(x₂ − x₁) = (14)/(-2) = -7.
Find the slope of the line through (3, -3) and (-3, -15).
- 4
- 2 ✓
- 3
- 1
Why: m = (y₂ − y₁)/(x₂ − x₁) = (-12)/(-6) = 2.
Write the equation of the line through (8, 8) and (6, 8) in slope-intercept form. What is the y-intercept b?
- 7
- 9
- 8 ✓
- 10
Why: Slope m = 0. Use y = mx + b: 8 = 0(8) + b → b = 8 = 8.
Write the equation of the line through (3, -1) and (2, 11) in slope-intercept form. What is the y-intercept b?
- 36
- 35 ✓
- 37
- 34
Why: Slope m = -12. Use y = mx + b: -1 = -12(3) + b → b = 35 = 35.
Write the equation of the line through (-2, 11) and (-6, -9) in slope-intercept form. What is the y-intercept b?
- 21 ✓
- 23
- 20
- 22
Why: Slope m = 5. Use y = mx + b: 11 = 5(-2) + b → b = 21 = 21.
For the line 6x + 6y = 12, find the y-intercept.
- 2 ✓
- 1
- 3
- 4
Why: Set x = 0: 6y = 12, so y = 2.
Common questions
Are these worksheets really free?
Yes. Free to print, free to practice online. No email, no sign-up, no paywall. We make money from optional paid features (toy redemption with real cents), not from the worksheets.
What TEKS standards does this cover?
This unit aligns to multiple Algebra I math TEKS standards.
How many total questions are available?
2,374+ questions in our Algebra I Linear Functions bank. Print as many 20-question worksheets as you like — each one pulls a fresh set so your kid doesn't see the same questions twice.
Where do these questions come from?
Generated by our AI pipeline, then quality-gated by two independent models (gpt-4o for content review, Claude Sonnet 4.5 for math verification) before publishing. Every question is tagged to a specific TEKS standard and modeled on real STAAR item shapes.
