Interpret the slope: H=−5t+100H = -5t + 100, where HH is heat (Joules) and tt is time (sec).

A

Heat is lost at 5 Joules per second

B

Heat is gained at 5 Joules per second

C

Initial heat is 100 Joules

D

Heat is lost at 100 Joules per second

Correct Answer: A

Choice A is the correct answer. Negative slope.

  1. Slope: −5-5.
  2. Meaning: Rate of change is negative (Loss).
  3. Units: Joules per second (Watts).

💡 Strategic Tip: Negative rate = Loss/Decrease.

Choice B is incorrect.Choice C is incorrect because intercept. Choice D is incorrect because wrong value.
