A screenshot of the Desmos calculator shows an equation, statistics, and a scatterplot with a line of best fit.The equation reads y subscript 1 baseline tilde m x subscript 1 baseline plus b. The word statistics appears below the equation along with the equations r squared equals 0.9891 and r equals 0.9946. The word residuals appears below the statistics and shows e subscript 1 baseline with a button labeled plot next to it. The word parameters appears below the residuals and shows the equations m equals 0.660818 and b equals negative 1,242.91. To the right of the equations is a scatterplot with a line of best fit. The equation of the line is y equals 0.660818 x minus 1,242.91. The points lie very close to the line.
Using the equation, predict the average temperature in the year 2050.

To predict the average temperature in the year 2050, you will need to substitute x = 2050 into the equation y = 0.660818x - 1242.91.
y = 0.660818(2050) - 1242.91
y = 1356.4459 - 1242.91
y = 113.5359
Therefore, the predicted average temperature in the year 2050 is 113.54.
The closest response option is 111.76.
