can you calculate slope with just coefficient of determination?

Solution

No, we cant calculate just with coefficient of determination

the coefficient of determination just give us an idea of how well the regression line
      represents the data.

The coefficient of determination represents the percent of the data that is the closest
      to the line of best fit. For example, if r = 0.922, then r ² = 0.850, which means that
      85% of the total variation in y can be explained by the linear relationship between x
     and y (as described by the regression equation). The other 15% of the total variation
      in y remains unexplained.
The coefficient of determination is a measure of how well the regression line
      represents the data. If the regression line passes exactly through every point on the
      scatter plot, it would be able to explain all of the variation. The further the line is
      away from the points, the less it is able to explain.
