Change from all posts to specific categories post on main page?

Question

How do I change my index.php to display only the desired categories posts in the main page ?

I tought that changing this would workout but instead it just print nothing:

            query_posts( array(
            'post_type' => array(
                        'post',
                        $include_reviews,
                        $include_screenshots,
                        $include_videos
                    ),
                    'paged' => $paged )
                );

Change from 'post', to 'cat=10', not very sure how to do this.

This is my index.php file:

<?php get_header(); ?>

    <?php
    $slider_number = get_option('lp_slides_number');
    $args = array( 'post_type' => 'slider', 'showposts' => $slider_number );
    $slider_loop = new WP_Query( $args );
    if ($slider_loop->have_posts()) : ?>
    <!-- BEGIN SLIDER -->
    <div class="slider">

        <div class="sliderContent">

        <?php while ( $slider_loop->have_posts() ) : $slider_loop->the_post(); $src = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), false, '' ); ?>
            <div class="featured-item" style="background:<?php echo get_post_meta($post->ID, 'feature_bg', true); ?> url(<?php echo $src[0]; ?>) no-repeat center; height:280px;">

                <div class="featured-inner">

                    <div class="featured-inner">

                        <div class="featured-arrows"></div>
                        <h1><a href="<?php echo get_post_meta($post->ID, 'feature_url', true); ?>" rel="bookmark" title="Link Permanente: <?php the_title(); ?>"><?php the_title(); ?></a></h1>
                        <p class="featured-meta">Por <?php the_author(); ?>, <?php the_time( get_option('date_format') ); ?></p>

                    </div>

                </div>

            </div>

                    );

Your syntax is wrong, change:

 query_posts( array(
                'post_type' => array(
                            'post',
                            $include_reviews,
                            $include_screenshots,
                            $include_videos
                        ),
                        'paged' => $paged )
                    );

to:

 query_posts( array(
        'tax_query' => array(
            array(
                'taxonomy' => 'category',
                'field' => 'slug',
                'terms' => array( $include_reviews,
                                $include_screenshots,
                                $include_videos )
            )),
        'paged' => $paged,
        'post_type' => 'post')
);
