(1.) Move slider 1, what characteristic of the line is changing?
(2.) Describe how the equation of the line changes as you move point A.
(3.) Move point A into Quadrant 3. Explain how the equation is different than before.
(4.) Using the above information, write the general form of point-slope form.
(5.) Write the equation of the line in point-slope form when the slope is -3 and the given point is (1,-4). Move the slider and the point to check your answer.
(6.) Rearrange this equation into slope-intercept form (y=mx+b). Move slider 2 to the right to check your answer.
