Baseball regression line prediction:
Suppose the equation for the regression line for the number of runs scored in a season, y, is given by $\displaystyle {y}=-{680}+{6900}{x}$, where $\displaystyle {x}$ is the team's batting average.
For a team with a batting average of 0.235, find the expected number of runs scored in a season.
Round your answer to the nearest whole number.
