Answer:
your slope will be -1
Step-by-step explanation:
if you do y-y and x-x you then divide those answers and you will end up with m=-1
Try to divide the diameter by two
If those are the possible answers i'm pretty sure you need to have a group of numbers you extract the mean from for example form the numbers 56, 77, 65, 87, and 99 the mean of the numbers would be 77 so once i have those we can figure it out
In the first one the options they give you are wrong, in fact you can prove it yourself, none of the options will give you as a result 10
I hope I helped you out
