Question

# Use the following data to determine a linear regression equation. (-3,4.5), (-2,4), (-2,3), (-1,3), (-1,2), (0,0), (0,1), (2,-1) Solution

Verified

Input the $x$-values of the given data points under $L_1$ in your graphing calculator. Then input the corresponding $y$-values under $L_2$. Using the LinReg(ax+b) feature on your graphing calculator then gives $a\approx-1.19$ and $b\approx1.02$ so the linear regression equation is $\boxed{y=-1.19x+1.02}$.
