STAAR EOC - Algebra I (Texas) Exam Survival Guide

Format: MCQ + griddable; TEKS-aligned

Must-do topics

• Linear functions: slope/intercept, graph ↔ table ↔ equation
• Systems of linear equations/inequalities (solve by graph/substitution/elimination)
• Quadratics: factoring, completing square, quadratic formula, vertex/axis
• Exponent rules & exponentials (growth/decay)
• Data models: scatter plots, correlation, best-fit lines; simple stats

Top traps

• Mixing slope units; sign errors in y=mx+by=mx+by=mx+b
• Solving systems but interpreting the wrong variable
• Forgetting ± in square-root steps
• Factor vs solve confusion (factored form ≠ solutions written)
• Treating correlation as causation

Quick checks

• Find slope/intercept from two points; write y=mx+by=mx+by=mx+b
• Solve: 2x+3=112x+3=112x+3=11; then a 2-eqn system
• Factor x2−5x+6x^2-5x+6x2−5x+6; roots?
• Classify data trend from a scatter plot

You will make

• Form switcher: table ↔ graph ↔ equation templates
• Quadratic toolkit: factoring patterns + formula card
• Systems gallery: 1 example per method with notes

Last-48h checklist

• 10 linear → equation/graph swaps
• 6 system solves (2 each method)
• 6 quadratic solves (mix of methods)
• 1 mini-set on exponent rules

1 data set → line of best fit (conceptually)
