## Slope-Intercept Form

#### Activity Overview

Students write linear equations in slope-intercept form and graph them. Students practice identifying slope and y-intercept and writing equations from a graphs.

This Activity comes from Prentice Hall's © 2007 Algebra 1 textbook.

#### Before the Activity

• Review the lesson PDF files
• Make copies of the lesson PDF files for your class
• Using LearningCheck Creator, review the LearningCheck™ EDC files prior to class. They include Check Skills You'll Need and Check Understanding questions from the lesson
• Make sure the LearningCheck App is on all student calculators
• Transfer the LearningCheck EDC files and Program file to student calculators using one of these methods:
• LearningCheck Creator "send to device" feature with a connectivity cable and unit-to-unit cables
• TI Connect, a connectivity cable and unit-to-unit cables
• TI-Navigator "send to class" feature

#### During the Activity

Students will:

• Learn to write linear equations in slope-intercept form.
• Graph linear equations.
• Practice identifying slope and y-intercept.
• Write equations from graphs.
• Write equations, given slope and y-intercept.
• Directions:

• Distribute the student activity sheets.
• Follow the procedures as outlined.
• #### After the Activity

As a class, review student progress, discussing questions that appeared to be more challenging, and re-teaching as needed.
