Best ResponseYou've already chosen the best response.0Examine the slopes from part A. As the xcoordinate gets closer and closer to 3, the slopes seem to approach what number? Note that some of the xcoordinates in part A approach 3 from below and some approach 3 from above.

Best ResponseYou've already chosen the best response.0No. You have slopes approaching from below of 4.444444, 4.040404, 4.004004, and 4.000400. You have slopes approaching from above of 3.636363, 3.960396, 3.996003, and 3.999600. They seem to be closing in on what number?

Best ResponseYou've already chosen the best response.0And for part C, you now have the slope (4) and the coordinates of point P so you can figure out the equation of the line.
