A screenshot of the Desmos calculator shows a table and a scatterplot.The table shows the following points: left parenthesis 1920 comma 29.9 right parenthesis, left parenthesis 1930 comma 34.7 right parenthesis, left parenthesis 1940 comma 37.2 right parenthesis, left parenthesis 1950 comma 42.6 right parenthesis, left parenthesis 1960 comma 50.6 right parenthesis, left parenthesis 1970 comma 57.5 right parenthesis, left parenthesis 1980 comma 64.1 right parenthesis, left parenthesis 1990 comma 70.4 right parenthesis, left parenthesis 2000 comma 79.7 right parenthesis, and left parenthesis 2010 comma 87.4 right parenthesis. These points are plotted on a graph to the right of the table. The point left parenthesis 2020 comma 93.8 right parenthesis is also plotted. The points appear to lie roughly on a line with positive slope.
Using the points listed in the table, calculate the line of best fit using technology.
