The invasive diatom species Didymosphenia geminata as the potential to inflict substantial ecological and economic damage in rivers. An article described an investigation of colonization behavior. One aspect of particular interest was whether y colony density was related to x rock surface area. The article contained a scatterplot and summary of a regression analysis. Here is representative data x 50 71 55 50 33 58 79 26

The second observation has a very extreme y value (in the full data set consisting of 72 observations, there were two of these). This observation may have had a substantial impact on the fit of the model and subsequent conclusions. Eliminate it and recalculate the equation of the estimated regression line. (Round your values to three decimal places.)y = ?
