Find the slope, the y-intercept, the x-intercept, and 1 other point on your graph.

Slope = -3504

Y-intercept = 642289

X-intercept = 183

Point = (10, 607249)- attendance in 2000 was 607249 on the line

Find the equation of the trend line.

y = -3504 x + 642289

Give the meaning of the slope and y-intercept from your data.

Slope is the attendance per year

Y-intercept the attendance the first year (1990)

Write three word problems based on your data.

1. Use the slope-intercept form of a line

2. Needs to use the slope-point form of a line or use the point-point form of a line.

3. Makes a prediction on future data (extrapolates).

1. The Orlando Magic organization began in 1990 and had an average attendance of 642,289 people that first year. Each year attendance has decreased by 3504. Write an equation of a line in slope-intercept form that represents the attendance (y) in terms of the years since 1990 (x).

2. The Orlando Magic had an average attendance of 607249 in 2000 (x = 10 - 10 years after 1990), if the attendance is dropping by 3504 each year write an equation of a line in slope-intercept form that represents the attendance (y) in terms of the years since 1990 (x).

3. Using the equation you found in question 1 or 2 above predict the average attendance in 2010.
