Desmos Slope review
Review of slope by Becky Hall.
Desmos Polygraph Lines
With Polygraph, Desmos provides tools for developing informal language into formal vocabulary. Because words should result from a need to describe our world—this is where they gain their power.
Desmos Polygraph Lines 2
This activity follows up on Polygraph: Lines, using the discussions (and students’ informal language) in that activity to develop academic vocabulary related to the graphs of linear functions.
Desmos Land the Plane
In this activity, students practice finding equations of lines in order to land a plane on a runway. Most of the challenges are well-suited to slope-intercept form, but depending on the goals of an individual class or student they are easily adapted to other forms of linear equations.
Desmos Slopes of Parallel and Perpendicular Lines
In this activity, students use sliders to investigate the slopes of parallel and perpendicular lines. By Brent Smith.

Desmos Put the Point on the Line
This activity’s focus is slope. The goal is to sharpen students’ focus on slope. In particular, the activity asks students to estimate first, then to calculate, then to notice proportionality as they place points on an imaginary line.
