LINESTX return 0 for slope

Hi Anonymous ,

There could be several possible reasons for this issue, such as:

- The data points in your table are not linearly related, meaning that there is no correlation between the x and y values. This could happen if the data is random, constant, or has outliers that distort the trend.

- The data points in your table have a very small variation in the x or y values, meaning that the slope is very close to zero but not exactly zero. Adjust the format of your measure to display more decimal places.
