SAT Math — Algebra (Set 2)

A second round of Algebra practice — fresh equations, systems, inequalities and functions.

Exam Tips for SAT Algebra

1. For systems of equations, check if adding or subtracting the equations eliminates a variable instantly.
2. Perpendicular lines have slopes that are negative reciprocals of each other.
3. Distribute first when solving equations with parentheses on both sides.
4. Double-check your answer by substituting it back into the original equation.
