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