What @will.H posted is perfectly valid.
If you're still not sure, here's a more detailed explanation with an example.

A typical proposition with conditional is
if \(hypothesis\) then \(conclusion\).
The contrapositive of the above statement is
If \(not~conclusion\) then \(not~hypothesis\).
A proposition and its contrapositive are logically equivalent.

Example:
For the proposition
"If it rains, then I bring an unbrella".
the contrapositive is:
"IF I do not bring an umbrella, then it does not rain".

Answer 8

Answer 9

nooo, i took that back tho, the Answer is C because the contrapositive is changing the order of the statements and negative the sentences. that's all

Well, if you still have difficulties with the examples, perhaps it's a good idea to let your teacher explain to you.
