Here's a prototype for showing how the
equation of a straight line changes as you change its slope (
m) and intercept (
b):
It starts with an
horizontal line along the x-axis, where the slope is zero and the intercept is zero:
The line moves upward, but stays horizontal, until the intercept is 1.0:
The slope increases from horizontal (m = 0), gradually, until the slope is 0.5:
Finally, we move the line upwards again, without changing the slope (m = 0.5), until the intercept is equal to 4.0:

Now I just need to figure out how to make them interactive.
