Published on 05/26/2005

Activity Overview

Students will identify x- and y-intercepts graphically. Students will calculate the slope between 2 points. Students will write the equation of a line in slope-intercept form when given the graph of the line.

Before the Activity

If you are using the TI-Navigator System with the TI-73 you will need the attached .pdf file.
Students should be comfortable with graphing in the coordinate plane. Provide students with definitions of x- and y-intercepts and slope. Show slope intercept form.

During the Activity

Students will identify x- and y-intercepts graphically. Students will calculate the slope between 2 points. Students will write the equation of a line in slope-intercept form when given the graph of the line.

After the Activity

Students complete the attached learning check document for assessment.
