Classes should have been able to check their previous night's homework and make sure they understood their mistakes.
Students helped each other with misunderstanding.
Then the class time was devoted to using notes and examples from the textbook and help from each other to solve problems related to midpoint and slope. Some problems had geometric figures with coordinates to interpret based on slope and midpoint.
I called this work in class HW #15. For A- day students it was an add-on to the previous night's homework.
Students should have read p 36-37 and then completed p 37:1-4, and the rectangle on #8, showing use of midpoint formula.
Students should have read p 133 about slope formula and then done 1-5 on p 134.
Students should have read p 165 through Example A on p 166 and the notes on the middle board about parallel and perpendicular. Complete homework by doing p 167:1-4, 7-11. On 7-9 you may just count rise and run to find the slopes of the sides of the quadrilaterals. On 1-4 and 9-11, you should use slope formula.
Midpoint formula is on p 33. Slope formula is on p 134.
If you finished in class, there was no homework.
