In this inquiry based, discovery activity students graph a line to find the slope and y-intercept and then compare those numbers to the equation. The goal of this activity is to help students make observations about the information that can be found in the equation of a line in slope-intercept form. Students construct their own meaning and understanding, and will be making observations and answering critical thinking questions that will help them to make sense of the equation of a line in slope-intercept form.
This download also includes two sets of two column notes pages on graphing lines in slope intercept form and writing equations of lines in slope intercept form given a graph.
Answer keys are included.
**This activity assumes that students already know how to find the slope of a line from a graph, create a table of values and plot ordered pairs.
