Graphs of Linear Functions
by Anonymous
Adjust the slope a and the y-intercept b to see how a line tilts and where it crosses, then match target lines and predict the points it passes through.
About this app
An interactive middle-school math app for exploring the graph of a linear function y = ax + b. Adjust the slope a and y-intercept b to see how direction, steepness, and the point where the line crosses the y-axis change. Practice by matching your line to dashed targets and solving point-on-the-line challenges.
Use cases
- Middle-school students learning linear functions
- Teachers demonstrating slope and y-intercepts
- Learners practicing graph interpretation
- Parents supporting at-home math study
Features
- Interactive graph of y = ax + b
- Controls for changing slope and y-intercept
- Explore missions on direction, flat lines, the origin, and slope size
- Match adjustable lines to dashed target lines
- Quiz mode for finding y-values at given x-values
