Mathematical Analysis of Temperature Scales
Young scholars use the point-slope formula to determine the relationship between the Celsius and Fahrenheit scales of temperature. They use a graphing calculator to determine the slope of the line between two points in each scale.

Point-Slope Form
Ninth graders explore the point-slope form of linear equations and graph lines in the point-slope form. After completing the point-slope equation, they identify the slope of a line through a particular point. Students explain the...

Linear Inequalities - Parallelogram Problem
Students use the Geometer's Sketchpad to illustrate possible answers to a parallelogram problem. As a class, they discuss the point-slope and linear equation forms. Individually, students solve their equations and check the results on...
