Explanation of linear equations and four types of slopes: positive, negative, zero, and undefined. Practice problems for the students are provided and a reinforcement activity using a graphing calculator is offered for the teacher's use.

Explore the relationship between degrees Fahrenheit and degrees Celsius. This video focuses on developing an expression to model the relationship between the temperature scales using a line graph to calculate slope and the y intercept.

Explains what the slope-intercept form is and how to find the equation of a line given two points on it. Includes modeled video lesson. [3:32]

This task asks students to identify when two quantitative variables show evidence of a linear association and to describe the strength and direction of that association. Students will use a scatterplot showing the finishing times for the...
