2013 Algebra I Mid-Term Exam Review Topics SOL A1, chapters 1 and 2 3 questions: Integer operations, Perimeter expressions, Distributing and Combining like Terms, area formulas, evaluate expressions SOL A4, chapters 3.3-3.4, 3.6, 3.8 2 questions: identify the properties 6 questions: solving equations, solving proportions, to include all real numbers and no solution 3 questions: word problems for equations/proportions SOL A5, chapters 6.1-6.3 5 questions: solving inequalities and graphing their solutions on a number line, to include all real numbers and no solution SOL A6, chapters 4.1-4.7 7 questions: to include horizontal/vertical lines, slope formula, finding slope and y-intercepts, given an equation-identify the graph 3 questions: given the slope and y-intercept or graph – write the equation of the line SOL A7, chapters 4.1-4.7 2 questions: is the item a function 2 questions: identify domain or range (read a graph and know limits) 3 questions: find the x- and y-intercepts or graph with the x- and y-intercepts 1 question: Find zeros of a function SOL A9, Statistics Unit Materials 3 questions: standard deviation and z-scores, mean/median/mode/range SOL A10, Statistics Unit Materials 2 questions: Box-and-whisker plots interpretation Vocabulary: Coefficient Domain/Range of a function Evaluate Slope Substitute Ordered Pair Constant Solution Vertical Line Test x-intercept Function y-intercept Linear Equation Direct Variation Linear Inequality Zeros Constant of variation Non-function Slope-Intercept form of a linear equation Mean Median Mode Quartiles Box-and-Whisker Standard Deviation Mean Absolute Deviation Z-score Limited domain/range Basic Skills (Chapter 1 and 2): While not directly assessed, inability to perform basic rational number arithmetic and keep control of signs, will result in inability to accurately perform the abovementioned skills. o o o o Fraction Operations: pgs. 912-915 Integer Operations: pgs. 77-79, 82-83, 91-92, 106-107 Order of Operations: pgs. 10-11 Distributive Property: pgs. 99-100 Big Ideas Equations and Inequalities with one variable (ex: 1 (3 x 7) 12 ) 2 What is true in an equation? What is a solution to an equation/inequality? How do we find a solution? Can I write a situation to represent the equation 4x 9 45 What is the equation of a horizontal line? What is the equation of a vertical line? Are all equations functions? What does it mean if an equation has “All Real Numbers” as a solution? What does it mean if an equation has “No Solution” as a solution? How do you graph a solution to an inequality on a number line? Linear Equations: What are they? How do we know they are linear? What is a solution to a linear equation? How can I tell an equation is linear by looking at it? What is slope? What does it tell me? What are synonyms for slope? How do I find slope? What kinds of slope are there? What does this mean? How can I graph a linear relationship? How can I write a linear relationship? What are functions? How do you determine if a relation is a function or not? What are zeros? How are they represented?
