Open the attached Calc-file and have a look at the equation.
Open the attached Calc-file.
There are values created for a x-y-chart with y=2.8*x
The chart has been created, the trend line also and the equation also.
The equation is wrong, shows f(x)=2.8x - 2.14...E-15.
Change the value in the chart from 2.80 € to 2.60 €.
Equation is right.
You have to switch "Force Intercept" to "0" to get the right equation also with
2.80 €.
Trend line doesn't recognize the right "start values" every time ...</pre>
