YES.  That is why I am confused.  This is the homework review for a test and I don't get it.  Perhaps is a mistake on the worksheet

1 , Would Equal Inverse If It Was Correct ,

Maybe it should be:
1. if a=3 and -3=d, then a=-d
Which is an example of the inverse property, where d is the inverse of a.

I don't entirely agree with your options. 
Question 3 looks like an example of the transitive property, i.e: a=b and b=c implies a=c.
