What does Linear Functions test on the SAT?

Linear Functions questions focus on constant rate of change, function notation, and how a line's equation or graph changes. They often ask for a value, rule, or interpretation rather than simply solving an equation.

Common question types

  • Evaluate or define a linear function
  • Compare rates of change
  • Describe a translation or parameter change

Common traps

  • Treating f(x) as multiplication
  • Confusing input and output values
  • Misreading how a coefficient changes slope or intercept

Difficulty distribution

Featured Linear Functions questions

How do I improve at Linear Functions?

  1. 1Translate function notation into input-output language.
  2. 2Find the constant change before choosing a formula.
  3. 3Check the rule with a known point from the graph, table, or context.

Desmos method

Graph the function and use point evaluation, intersections, or sliders for unknown parameters. A table is often the fastest way to compare outputs at specified inputs.
