1. Graph these points on graph paper.[br][br] Draw the line of best fit. Find its equation.[br][br] Check the box to see if your line agrees with the computer.[br][br][br][br]2. You can move the points to try a new example.[br][br][br][br]3. Move one or more points to see what effect it has on the line of best fit.[br][br] (Does the line of best fit have to go through any of the points?)[br][br][br][br]4.
