See how the slope and y-intercept change the graph of an equation of a line.

- Click here for the slope slider activity. If this link does not work: click here.

**Directions:**

- For this Slope Slider activity, you will be working with the graph of a linear equation. Moving the purple bar at the bottom of the page will change the value of the slope. Moving the green bar at the bottom of the page will change the value of the y-intercept.

- After you are finished experimenting, answer the following questions:
- What happens to the graph as the purple number, or slope, becomes larger?
- What happens to the graph as the purple number, or slope, becomes smaller?
- What happens to the graph as the purple number, or slope, is positive?
- What happens to the graph as the purple number, or slope, is negative?
- What happens to the graph as the purple number, or slope, is zero?
- What happens to the graph as the green number, or y-intercept, becomes smaller?
- What happens to the graph as the green number, or y-intercept, becomes larger?
- What happens to the graph as the green number, or y-intercept, is zero?

**Algebra vs. The Cockroaches**

Directions:

- Watch the instructions before playing the game!
- The cockroaches will move along a straight line. Your mission is to find the equation of the line in slope-intercept form.
