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.
