How to display category for posts?

Question

Laravel

I am using a many-to-many relationship.
It is necessary to display a list of posts, which category the post belongs to, I did it using the builder, because I don’t know how to do it through the ORM.
3 tables:
categories
-id
-name
images
-id
-image
-description
category_image (intermediate)
-image_id
-category_id

public function getCategoryTitle($id)
    {  
        $post = DB::table('category_image')
                     ->where('image_id', '=', $id)
                     ->get();
        $categoryImage = $post->toArray()[0]->category_id;
       
       
        $showCategory = DB::table('categories')
                     ->where('id', '=', $categoryImage)
                     ->get();
       
       return $showCategory->toArray()[0]->name;
       
    }

Now it turns out that for each post, there will be 2 more requests to the database, and this is very bad.
posts like this

public function index()
    {
        $posts = Image::all();
     
        return view('admin.posts.index', ['posts'=>$posts]);
    }

@foreach($posts as $post)
                <tr>
                  <td>{{$post->id}}</td>
                  <td>{{$post->description}}</td>
                  <td>{{$post->getCategoryTitle($post->id)}}</td>
                  <td>

/////////////////////////////////////////////////// ////////////////
Tried with ORM

dd( $this->belongsToMany(
            Category::class,
            'category_image',
            'image_id',
            'category_id',
                1
        ));

And how now to display the name of the category?

Answer 1

I did something like this
Model for articles:

class Articles extends Model
{
    protected $table = 'article';

    public function category()
    {
        return $this->belongsTo('ArticlesCategory', 'id_category', 'id');
    }
}

Model for categories:

class ArticlesCategory extends Model
{
    protected $table = 'article_category';

    public function articles()
    {
        return $this->hasMany('Articles', 'id_category', 'id');
    }
}

We get articles with categories in the controller In the template like this:
$article->category->name
