1. Elementary Algebra A review of concepts and computational skills Chapters 3-4

2. Linear Equations and their Graphs Graphing points and lines Coordinate system Quadrants x-axis and y-axis Ordered pairs (x, y) Graphing linear equations Ax + By = C using x|y tables (ordered pairs) Horizontal and Vertical lines

3. Slope Slope- steepness of a line Change in y / change in x Rise over run Find slope from graph Find slope given 2 points Slope for horizontal and vertical lines Graph a line given slope and a point on the line Parallel and perpendicular lines

4. Equations of Lines in Slope-Intercept Form Slope-intercept form: y = mx + b Use to graph a line Write an equation given slope and y- intercept

5. Point-Slope Form Point-slope form: y - y 1 = m(x – x 1 ) Write an equation given point and slope Write an equation given 2 points

6. Systems of Linear Equations and Inequalities Graphing a system of equations Solving by graphing Independent, dependent and inconsistent systems and their graphs Substitution method Elimination method Graphing linear inequalities and systems
