#### 8.1: Analyze and represent linear functions, and solve linear equations and systems of linear equations.

8.1.1: Translate among contextual, verbal, tabular, graphical, and algebraic representations of linear functions.

8.1.2: Determine the slope of a line and understand that it is a constant rate of change.

8.1.3: Identify and interpret the properties (i.e. slope, intercepts, continuity, and discreteness) of linear relationships as they are shown in the different representations and recognize proportional relationships (y/x = k or y = kx) as a special case.

8.1.4: Use linear functions and equations to represent, analyze and solve problems, and to make predictions and inferences.

8.1.5: Relate systems of two linear equations in two variables and their solutions to pairs of lines that are intersecting, parallel, or the same line.

8.1.6: Use informal strategies (e.g., graphs or tables) to solve problems involving systems of linear equations in two variables.

#### 8.2: Analyze and summarize data sets.

8.2.1: Organize and display data (e.g., histograms, box-and-whisker plots, scatter plots) to pose and answer questions; and justify the reasonableness of the choice of display.

8.2.2: Use measures of center and spread to summarize and compare data sets.

8.2.3: Interpret and analyze displays of data and descriptive statistics.

8.2.6: Use sample data to make predictions regarding a population.

8.2.8: Use data to estimate the likelihood of future events and evaluate the reasonableness of predictions.

#### 8.3: Analyze two- and three-dimensional spaces and figures by using distance and angle.

8.3.2: Use models to show that the sum of the angles of any triangle is 180 degrees and apply this fact to find unknown angles.

8.3.4: Use models to explore the validity of the Pythagorean Theorem, and use it to find missing lengths.

8.3.5: Apply the Pythagorean Theorem to find distances in a variety of 2- and 3-dimensional contexts, including distances on coordinate graphs.

8.3.6: Use models and referents to explore and estimate square roots.
