## Show Notes

- in-class exercise [pdf] and solutions [pdf].
- We also derived formulas [pdf] for the slope and intercept of the (much more convenient!) regression equation y = mx + b. The derivations are not important, but you should be able to use the formulas to find m and b. You should also be able to use the equation to predict y from x (and to the other review exercises from ch. 12). See ch. 12 below for all the details.
