Students investigate intercepts, slope, parallel and perpendicular lines. A Business Venture Students investigate increasing and decreasing lines and zero and undefined slopes. Lesson 5 The Bouncing Ball Students collect data for use in examining linear behavior and making predictions. They learn to distinguish between dependent and independent variables. Lesson 7 Driving Us Crazy Students determine that slope is a constant along the graph of a linear equation.
Students use a graphing calculator to display data and determine a formula for the line of best fit.
Students distinguish between formula domain and range and problem domain and range. Students work backward from a given output to find the corresponding input. Story Time Students examine some examples of non-linear behavior. Students examine the relationships between graphs and verbal descriptions.
