[size=100][size=150][b][right][/right]Move point B to create a line with the given slope.[br][/b]Point A starts at the origin, but you may also move it to see how lines with the same slope shift in position.[br]Explore different slopes and observe how the steepness and direction of the line change.[/size][/size]

1. How does the line look when the slope is [b]positive[/b]?[br]2. How does the line look when the slope is [b]negative[/b]?[br]3. What do you notice about the line when the slope is [b]zero[/b]?

1. If the slope is [math]m=2[/math], how do you expect the line to tilt? How about when it is [math]m=-2[/math]?[br]2. If the slope is [math]m=-\frac{1}{3}[/math]how will the line move as you go from left to right? How about if the slope is [math]m=\frac{1}{3}[/math]?[br]3. What would a line with a very large slope (example [math]m=10[/math]) look like? How about when the slope is [math]m=-10[/math]?
