Use the sliders to change the y-intercept equation to match the Standard Form equation. Click on the blue arrows in the upper right for a new equation. Click on a point and use your arrow keys to move it.

- Adjust the slope intercept form (the blue slides) to match the standard form equation line.
- Move the point on the red line so the point slope form matches the slope intercept form.
- Explain how these three equations are alike.
- Explain how these three equations are different
