2. Pp161-162 AddPrac Investigation 2
OBJECTIVE: oTo recognize linear relationships from tables: for each unit change in one variable, there is a constant rate of change in the other variable. oTo determine whether a set of data is linear by examining its graph. oTo recognize how the rate of change between two variables is associated with its representations. oTo recognize that a change in rate will change the steepness of a line and the coefficient of x (the independent variable). oTo interpret the meaning of the coefficient of x and the y=intercept of a graph of y=mx+b [1.5.1, 1.5.2, 1.5.3, 1.5.4, 2.2.1, 2.2.2, 3.1.1, 4.1.2, 5.2.1]; oTo connect solutions in graphs and tables to solutions of equations. oTo find a solution common to two linear equations by graphing. oTo understand how the y-intercept appears in tables and equations. oTo understand how the rate of change (the coefficient of m) appears in equations and affects the graph of a line. [1.5.1, 1.5.2, 1.5.3, 1.5.4, 2.2.1, 2.2.2, 3.1.1, 4.1.2, 5.2.1] ACTIVITIES/ASSESSMENT: Finish and correct investigation 2 additional practice.
