SAT Linear Functions Worksheet
Linear functions are the most common Algebra topic on the Digital SAT. You need to read slope and y-intercept out of tables, graphs, and verbal descriptions, and translate between those forms fluently — especially under word-problem pressure. This worksheet page turns that skill into a focused review asset: what to know, what to practice, and what to check before moving on.
What this worksheet covers
Linear Functions belongs to the Algebra domain on the Digital SAT Math section.
Use this as a one-skill worksheet before timed modules. The goal is not just to get questions right, but to recognize the pattern quickly under SAT timing.
- Official skill: Linear functions
- Section: Math
- Domain: Algebra
- Best use: focused drill session before a timed module
Rules to remember
Before drilling this skill, memorize the core rules below and keep them next to your scratch work.
- Slope = change in output / change in input — use two clean points from a table or graph.
- y-intercept is the value of the function when the input variable equals zero.
- In word problems, label units on the slope and intercept before you solve.
Practice routine
Start untimed until you can explain the pattern. Then switch to timed sets so the skill holds up inside a full module.
- Do 10 warmup questions and write down every mistake type.
- Do 20 timed questions from the same skill.
- Review missed questions without looking at the explanation first.
- Repeat the misses 48 hours later to confirm the fix stuck.

FAQs
How do I practice SAT linear functions?
Drill linear functions as its own skill first, then mix it into timed modules. Isolated practice builds the pattern; timed modules prove you can use it under pressure.
Is linear functions important on the Digital SAT?
Yes. It is part of the official Algebra domain for the SAT Math section, so it can appear on real test forms.
Should I review explanations after every question?
Review every missed or guessed question. Correct guesses still hide weak reasoning, and weak reasoning becomes expensive on hard Module 2.
