Day 1

 

Unit 5 - Day 1

 

Daily Objective: Students will use the line of best fit to find equations of lines.

 

Definition: A line on a graph showing the general direction that a group of points seem to be heading.

 

Pictures:  This picture shows a good illustration of how the line of best fit is drawn out on a graph. This line clearly shows that the data on a scatter plot.
