Point-Slope Form

The line below can be manipulated by moving slider 1 and point A. Please answer the questions below.
(1.) Move slider 1, what characteristic of the line is changing?[br](2.) Describe how the equation of the line changes as you move point A.[br](3.) Move point A into Quadrant 3. Explain how the equation is different than before.[br](4.) Using the above information, write the general form of point-slope form.[br](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.[br](6.) Rearrange this equation into slope-intercept form (y=mx+b). Move slider 2 to the right to check your answer.
