Question

Can someone explain slope? 17, 19, 21!! I can't understand and everytime someone it explains it they never do a good job

Answer 1

I know it looks really complicated because of how much I wrote, I just wanted to make sure you knew why I did what I did and give some justification and key points when it comes to finding the slope. If you want me to explain how to do this in y=mx+b form I can do that too, just let me know:) the answers are(17.) -1 (19.) 7 (21.) 2.
