Question

A researcher is investigating possible explanations for deaths in traffic accidents. He examined data from 2000 for each of the 52 cities randomly selected in the US. The variables were death and income.
Deaths: The number of deaths in traffic accidents per city
Income: The median income per city

The researcher ran a simple linear regression model: Deaths = Bo+B1(Income). Results shown in photo below.

Question: Please help me better understand how to use results from photo to find value of R-squared of this simple linear regression model.
