At the start of class we did a practice mental math. Then we #1.b on the "What Should I Be Able To Do" sheet.
To do regression we used linreg, quadreg and expreg. To find the R value from above hit the keys, stat calc then either linreg, quadreg or expreg. To paste it into the y= hit y=, vars, statistics,EQ,RegEQ then hit enter. The points that are in the statplot will now be on the graph. If they do not show up hit zoom 9. If they are still not there check to make sure the plot is on by going 2nd y= then turn it on.
