In this technology based activity, students will use Desmos.com to gain understanding of writing equations of lines in Point Slope Form and finding Domain and Range. Students are given a link to a Desmos shooting star
design which has been made with tables. They are asked to find the equation of each line used to make the design. Students are open to write equations in slope intercept form or point slope form, however, point slope form is easier for this activity. Students are also asked to make connections between parallel lines and their equations.
The beauty of this interactive activity is, by using Desmos, students are able to trial and error while not having to erase and restart as they would on paper. They can explore with various values of slope, points, domain, and range to see how the change in these values affects the sketch of the line.
In addition to the main activity, a remedial level of the activity is provided. This lower level version is a cut and paste activity with all the equations, domains, and ranges provided to the student. An answer key is provided for both the main activity and the cut & paste activity. Another option for remediation, is to allow students to write the equations based on the tables that are provided.
