[size=150][color=#0b5394]Consider the line segment AB shown below. You may imagine it as ramp. Then obviously slope of the ramp would be the ratio of the[/color][color=#980000] [b][u]rise [/u][/b][/color][color=#0b5394]of the point B from A to the [/color][u][b][color=#a61c00]run[/color][/b][/u][color=#0b5394][br](how much it is away horizontally) from the point A. [/color][/size]

[size=150]Drag the points A and B to different locations and observe how the slope is determined.[/size]
