You simply grab an (or multiple) object(s), manipulate them and call SaveChanges on the context. Of course, the object has to be attached to the context and tracking must enabled.

var obj = context.table.First(o => o.ID == 1);
obj.Property1 = data;
context.SaveChanges();

Taken from Employee Info Starter Kit, you can consider the code snippet as below:

public void UpdateEmployee(Employee updatedEmployee)
        {
            //attaching and making ready for parsistance
            if (updatedEmployee.EntityState == EntityState.Detached)
                _DatabaseContext.Employees.Attach(updatedEmployee);
            _DatabaseContext.ObjectStateManager.ChangeObjectState(updatedEmployee, System.Data.EntityState.Modified);
            _DatabaseContext.SaveChanges();
        }
