Default Chart daily data and add a trend line for each week

Excel 2003
Is there a way to create a chart using daily data and create a trend line
for each week. The data does not have an Saturday's or Sunday's.

My data looks like this.

Date Output Input
2/15/2010 229 215
2/16/2010 441 153
2/17/2010 205 43
2/18/2010 283 138
2/19/2010 609 121

Default Chart daily data and add a trend line for each week

To use Excel's built-in trendline feature, you need a separate series
for each set of points you want analyzed by a trendline. That means one
series for each week.

Alternatively, you could use SLOPE() and INTERCEPT() worksheet functions
to compute the line of best fit for each week, then calculate X and Y
values for the endpoints of each week's line, and plot each pair of
points as a new series.

I have the Slope & Intercept calculations, How do I calculate the X & Y
values from this?

Slope is m and Intercept is b. For desired values of X, calculate Y
using the well known formula

Y = mX + b

With X and Y in adjacent columns, plot each segment as a new series in
the chart.
