PART A Region: WA- Washington Essential Academic Learning Requirements Framework-Grade Level Standards (2012) Subject: Mathematics, 2008 Grade level: High School Algebra I (Ninth Grade) Standard: A1.4. Linear functions, equations, and inequalities (Algebra) Students understand that linear functions can be used to model situations involving a constant rate of change. They build on the work done in middle school to solve sets of linear equations and inequalities in two variables, learning to interpret the intersection of the lines as the solution. While the focus is on solving equations, students also learn graphical and numerical methods for approximating solutions to equations. They use linear functions to analyze relationships, represent and model problems, and answer questions. These algebraic skills are applied in other Core Content areas across high school courses. PART B Ninth Grade Algebra 1 A1.4. A Write and solve linear equations and inequalities in one variable 2 A1.4. B Write and graph an equation for a line given the slope and the y-intercept, the slope and a point on the line, or two points on the line, and translate between forms of linear equations 3 A1.4.C Identify and interpret the slope and intercepts of a linear function, including equations for parallel and perpendicular lines. (Perma-Bound, 2016) PART C Write and solve linear equations and inequalities in one variable. C1. On a multiple-choice quiz, students will be given ten-word to convert to
