You need to create a view model and use that. view model's are simple POCO classes which are specific to the view.

public class CustomerInfo
{ 
  public string Name {set;get;}
  public string AddressLine {set;get;}
}

And in your GET Action, you can create an object of this, read the data from 2 tables and set the property values of our view model and send to the view

public ActionResult View(int id)
{
   var vm = new CustomerInfo();
   var db=new YourDbContext();

   var customer=db.GetCustomer(id); // read from first table
   var address=db.GetAddress(id);   // read from second table
   vm.Name = customer.FirstName;
   vm.AdddressLine = address.AddressLine1;
   return View(vm);
}

And your view will be strongly typed to this view model

@model CustomerInfo
<h2>@Model.Name</h2>
<h3>@Model.AddressLine1</h3>

If you are trying to save this information to the db tables, You may have a form in your view

@model CustomerInfo
@using(Html.BeginForm("Edit","Home"))
{
 <label>Name</label> @Html.TextBoxFor(f=>f.Name)
 <label>Name</label> @Html.TextBoxFor(f=>f.AddressLine)
 <input type="submit" />
}

and in your HttpPost action

[HttpPost]
public ActionResult Edit(CustomerInfo model)
{
   // read the values from model and save to 2 tables
   var c=new Customer { FirstName=model.Name};
   var a=new Address{ AddressLine1=model.AddressLine};

   var db=new YourDbContext();
   db.Customers.Add(c);
   db.Addresses.Add(a);
   db.SaveChanges();
   return RedirecToAction("Success");
}

If you want to save a collection of items, You may refer this answer or this.
