For more information, please see the documentation here (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_defining_methods.htm?q=method) and this (https://trailhead.salesforce.com/en/content/learn/modules/object-oriented-programming-for-admins/create-classes-and-objects) trailhead to help further explain Object Oriented Programming concepts in Apex. Something below should at least help get you started, but let me know if you need any further explanation.
  
public void createLeadTask(Lead masterLead, Lead oldLead){
    Task leadTask = new Task();
    leadTask.WhoId = masterLead.Id;
    leadTask.OwnerId = masterLead.OwnerId;
    leadTask.Subject = 'Matched Lead - Follow Up';
    leadTask.Status = 'In Progress';
    leadTask.Priority = 'High';
    leadTask.Description = 'Old Matched Lead Info \nLead Record Id :- '+oldLead.Id+'\nLead Name :- '+oldLead.Name+'\nEmail Address :- '+oldLead.Email+'\nMobile Phone :- '+oldLead.MobilePhone+'\nInstagram Handle :- '+oldLead.Instagram_Handle__c+'\nWebsite :- '+oldLead.Website+'\nInterested Event Locations :- '+oldLead.Interested_Event_Locations__c+'\nVendor Type :- '+oldLead.Vendor_Type__c+'\nItems Interested In Selling :- '+oldLead.Items_Interested_in_Selling__c+'';
    insert leadTask;
    
    System.debug(masterLead);
    Database.MergeResult results = Database.Merge(masterLead, oldLead, false);
    System.debug(results);
}

This can be called as follows: 
createLeadTask(masterLead, oldLead)

I'm not 100% sure what you're trying to do here. Are you wanting to create a new method to create the Task so you can call that function from anywhere in your code?
