## Reflection: Lesson Planning How Much for a Used Car? - Section 2: Investigation

I ask my students to make both graphs by hand. I do use graphing technology quite a bit in my class, but for now I want students to practice plotting points by hand and determining scale. A nice follow up activity to this one is to have students use technology to create the scatter plots and then determine the correlation coefficients.
