Slope-Intercept Form Explorer

Run Fullscreen

About This MicroSim

This interactive tool lets you explore the slope-intercept form y = mx + b by adjusting sliders for slope (m) and y-intercept (b). Watch the line change in real-time as you modify the equation parameters.

How to Use

1. Adjust Slope (m): Move the left slider to change the steepness and direction
2. Adjust Y-intercept (b): Move the right slider to shift the line up or down
3. Observe Changes: Watch how the line and equation update instantly

Controls

Slider	Range	What It Controls
Slope (m)	-3 to 3	Steepness and direction of the line
Y-intercept (b)	-5 to 5	Where the line crosses the y-axis

Line Colors

Color	Slope Type
Red	Positive slope (rises left to right)
Purple	Negative slope (falls left to right)
Green	Zero slope (horizontal line)

Learning Objectives

• Apply slope-intercept form to graph lines
• Analyze how changing m and b affects the line
• Evaluate the relationship between equation parameters and graph
