Designed for beginning Algebra and Pre-Algebra students to introduce the concepts of slope and y-intercepts, this activity has students try to match a given line by typing in the equation. In the process, they will build their understanding of the meanings of slope and y-intercept, and writing equations in slope-intercept form. Using Activity Center, students try to write an equation that matches a given line.
Before the Activity
Prerequisite skills: Students should understand how to graph a function on the coordinate plane from an input-output table and know that the graph of a linear function is a line.
During the Activity
In this TI-Navigator Activity Center activity, students will determine the equation of a line, given the graph of the line. See the attached .pdf file for complete instructions and the attached .act file for the Activity Center settings.
After the Activity
