Find the line of best fit given the data below egin{tabular}{ |c|c|c|c|c|c| } hline x & 2 & 3 & 4 & 5 & 6 \ hline y & 6.4 & 7.5 & 8.5 & 11.5 & 15.0 \ hline end{tabular} Note that y = a + bx Find $n$, $sum x$, $sum y$, $sum x^2$, $sum y^2$, $sum xy$, $b = frac{n(sum xy) - (sum x)(sum y)}{n(sum x^2) - (sum x)^2}$ Remember to find a.

Determine the equation of the line of best fit from the data in the table on the right. The equation of the line of best fit is y = x + . (Round the slope and y-intercept to the nearest tenth.)
