The temperature C, in degrees Celsius recorded by a city park's weather station between midnight and 7am could be represented as a linear function of the number of hours after midnight, t. The temperature at 1:30am was −4.2°C

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

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

The correct equation to represent this function is C(t)=−0.8t−4.2.
