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) 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
The correct equation to represent this function is:
C(t) = -1.25t - 4.2
