Linear Equations in Standard, Point Slope and Slope Intercept Form

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.

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