First you have to select the partition by clicking on the partition you wish to delete. If the minus sign is greyed out that means you are attempting to delete the first partition on the drive and the first partition on the drive CANNOT be deleted. Select the other partition and the minus sign should no longer be greyed out, but if you delete that partition you will lose all the data on it.

I presume you mean you have turned on Filevault for that volume. You will have to do that in System Preferences > Security & Privacy > Filevault and you will need an empty volume of the same size to decrypt to and I would encourage doing that first as removing a partition has been known to cause data loss.
