How to delete data from relation

Hello, I have 3 tables. locations (Location model) categories (Category model) location_category (hasn't model)

in the Location model, I have the "categories" function

public function categories()
{
    return $this->belongsToMany(Category::class, 'location_category', 'location_id', 'category_id')
        ->withPivot('category_name', 'primary_category')
        ->withTimestamps();
}

in the Category model, I have the "locations" function

public function locations()
{
    return $this->belongsToMany(Location::class, 'location_category', 'category_id', 'location_id')
        ->withPivot('category_name', 'primary_category')
        ->withTimestamps();
}

I want to delete location_category data where 'location_id' column = $locationId. How can I delete that if I know that the "location_category" table hasn't model?
