It's due in like 10 plz help it's an easy question I'm juss stupid

Answer:
C
Step-by-step explanation:
Pls choose C, it goes from 12 to -4. that's a -16 difference. Over 4 units ([-2,2]), that's -16/4. It's not A because it goes from -4 to 12. That's a 12 difference, making it positive 4 instead of negative 4
