Question

and was −8.6°C
at 7am. Which equation could be used to represent this function?(1 point)
Responses

C(t)=−1.25t−8.6
cap c times t is equal to negative 1 point 2 5 t minus 8 point 6

C(t)=−1.25t−4.2
cap c times t is equal to negative 1 point 2 5 t minus 4 point 2

C(t)=−0.8t−3
cap c times t is equal to negative 0 point 8 t minus 3

C(t)=−0.8t−4.2

Answer 1

cap c times t is equal to negative 0 point 8 t minus 4 point 2
