Answer:
Most likely A, maybe b not c
Step-by-step explanation:
the whole exam will be 100%, and let's say that's "x" questions, but we also know that 9 is 60% of that so

The answer is B/C.—M is in fact NOT a midpoint of line AB. This is because to be a midpoint the distance between both endpoints and the midpoint must me equal. If AB has equaled 28 then is would be, but in this case NO. To get AM you just need to do 27-14. AM would be 13 (if you need that too)
? = 3
-12/-4 = 3
you can check your answer by plugging it into the variable
Graph the points and connect them and draw vertical lines in between them. You can already tell it's a function because every input has exactly on output.
