Answer 5

Let's take a look at case 1 first

We increase the temperature in Fahrenheit by 1, will the temperature in Celsius change by 5/9?

let's see
C=5/9(F−32)

Let's first say that we have 32 Fahrenheit
what would you get?

C = 5/9 (32- 32)
C = ?

Answer 6

And after you calculate that, let's use 33 Fahrenheit. So that way we can test option 1. What happens when we increase the temperature by 1 F

So we have

C = 5/9 (33-32)
C = ??

Is the difference between the first answer and this one 5/9?

If so, that makes condition 1 true
