How to call a method

I have an interface:

        void InsertPersonActivityLog(PersonActivityLog dateTime, PersonActivityLog typeDefinition, PersonActivityLog details, Person edi, Person firstName, Person middleInitial, Person lastName, PersonActivityLog message, PersonActivityLog notes);

The method for that interface  is:

public void InsertPersonActivityLog(PersonActivityLog dateTime, PersonActivityLog typeDefinition, PersonActivityLog details, Person edi, Person firstName, Person middleInitial, Person lastName, PersonActivityLog message, PersonActivityLog notes) // how to EF executes SP's
        {
            /// TO DO insert or add these to my table syntax
            /// cmd.Parameters.AddWithValue("@LogId", log.LogId);
            /// cmd.Parameters.AddWithValue("@Edi", log.Edi); // and so on
        }

In my service I have a login method that calls:

public void Login(Person person)
        {
            PersonActivityLog log = new PersonActivityLog();
            Person login = new Person();
            log.ActivityDatetime = DateTime.UtcNow;
            log.ActivityTypeDefinition = "Registration Status";
            log.AdditionalDetails = "Visitor";
            login.Edi = person.Edi;
            login.FirstName = person.FirstName;
            login.MiddleInitial = person.MiddleInitial;
            login.LastName = person.LastName;
            log.ReasonMessage = "Emtpy";
            log.Notes = "visited the site";
            InsertPersonActivityLog(DateTime.Now, log.ActivityTypeDefinition, log.AdditionalDetails, login.Edi, login.FirstName, login.MiddleInitial, login.LastName, log.ReasonMessage, log.Notes);
        }

But how do I call my method from here (in the service)?

private void InsertPersonActivityLog(DateTime now, string activityTypeDefinition, string additionalDetails, string edi, string firstName, string middleInitial, string lastName, string reasonMessage, string notes)
        {
            _personActivityLogRepository.InsertPersonActivityLog( what goes here???)
        }
