Interactive linear function
Drag the sliders and see how the slope and y-intercept affect the line in real time.
The linear function:
f(x) = ax + b
a = slope (steepness) · b = y-intercept (where line crosses y-axis)
a — slope
2
b — y-intercept

What does the slope tell us?
A straight line is the shortest distance between two points — and the clearest path through mathematics.
