Answer:
C
Step-by-step explanation:
Since the graph hits 0 at x = 0, your y intercept is 0.
The graph is decreasing which means you have a negative slope.
They gave you a coordinate so use it to find the slope.

That's your slope.
C is the correct answer.
Temperature, thermal conductivity, thermal diffusivity, and thermal expansion are all different properties of heat.
-40-8=12x
-48=12x
-48/12=x
-4=x
Answer:
I think the temperature went down 86° but I'm not sure
6x-3 this ? I don’t how you want it but hope it’s this ?
