Algebra I (Grade 9–10 Core Math) Exam Survival Guide

Must-do topics

• Expressions & Equations: simplify polynomials, factor quadratics, solve linear & quadratic equations (graph, factoring, formula).
• Functions: linear, quadratic, exponential basics; slope–intercept & standard form; domain/range.
• Inequalities: solve & graph 1- and 2-variable inequalities; systems of inequalities.
• Statistics: line of best fit, interpreting scatter plots, correlation.
• Real-World Applications: growth/decay models, rate problems, optimization.

Top traps

• Mixing slope forms (point-slope vs slope-intercept).
• Factoring sign mistakes (x² – 5x + 6 = (x–2)(x–3)).
• Graphing inequality: forgetting dashed line for “<” or “>”.
• Confusing correlation with causation.
• Forgetting ± when square-rooting.

Quick checks

• Solve: 2x + 3 = 9.
• Factor: x² – 9.
• Graph y = –2x + 5 → slope, intercept.
• Solve system: y = 2x + 1 and y = –x + 4.
• Interpret scatter plot: positive/negative correlation?

You will make

• Slope Triangle Sketches (rise/run practice).
• Quadratic Factoring Flash Cards.
• Inequality Graph Sheets.
• Scatter Plot Projects (real-world data like height vs shoe size).

Daily plan (40 min)

• 10 min fluency (equations/factoring drills).
• 15 min graphing & interpretation.
• 15 min word problems/applications.
