Use Quick Poll with Slope and Y-Intercept

Published on 06/09/2008

Activity Overview

When introducing slope and y-intercept to my students I find it helpful to change one variable, while holding the other constant. For example, I might show 2 graphs with identical y-intercepts, but differing slope, etc.

Before the Activity

Make sure students know how to respond to a quick poll. Review the attached documents for sample equations and screens.

During the Activity


  1. Students should enter Navnet
  2. Teacher verbally prepares quickpoll question such as "What is the slope and y-intercept of the following equation?" and types into the open field "y = -3x + 19".
  3. Send Quick Poll.

After the Activity

I often will analyze my student's results and have them work though the incorrect answers to find the error.
