The quality and the accuracy of the graphs The accuracy of the equations obtained by using the graphing calculators. Scavenger hunt to search the web for data for the extension assignments. Teachers can just give students the programmed guide and let students learn at their own pace. Students express quantitative relationships using algebraic terminology, expressions, equations, inequalities and their graphs. 1.5 represent quantitative relationships graphically and interpret the meaning of a specific part of a graph in terms of the situation represented by the graph 4.
Students solve simple linear equations and inequalities over the rational numbers.
Students collect, organize and represent data sets that have one or more variables and identify relationships among variables within a data set both manually and by using an electronic spreadsheet program. Students use strategies, skills and concepts in finding solutions. Students verify that a point lies on a line given an equation of the line. Students are able to derive linear equations using the point-slope formula. Students solve a system of two linear equations in two variables algebraically, and are able to interpret the answer graphically.
