This sheet has 12 sets of points, all conditionally formatted to give students immediate feedback. They will look at the points, calculate the slope, and type their answer in the yellow boxes. Immediately they will know if their answer is correct.
You will be immediately prompted to make a copy. Then the sheet will be yours and you can edit it if you feel it's necessary. This will be ready to post to google classroom (make sure you make a copy for each student).
Grading is a breeze! You will look at the thumbnails in Google Classroom and see if their answers are correct.
To see answers, click on the cell you are typing in, click format, and conditional format. I wouldn't do this in front of your students unless you want them to know how to cheat!
This is also great as sub plans!
