These web-based activities were developed, during summer sessions from 1997 through 1999, by students at Mainland High School, located in Daytona Beach, FL. As part of Mainland's CCTT grant, the students were given permission by the book's publisher to convert the ancillary materials of the County's adopted Algebra 1 textbook (Glencoe Algebra 1 — ISBN: 9780028253282) into html format.

| After plotting your data on graph paper (remember to place a tight, small circle around each data point), draw the line of best fit line through your data. Remember that a line of best fit does NOT have to pass through any of the data ... it averages the data's behavior. Finally, draw a small arrow pointing to the positions of two grid points through which your line passes. |
| The co-ordinates of your grid points are: ( ______, ______ ) and ( ______, ______) | |||
|
|||
| Use these points to calculate the equation of your line. Show your work. | |||
