Can't access data property from parent in slot child component

I have two components rad-list and rad-card, I placed a slot element in rad-list where I will place rad-card, now rad-card receices an object from computedResults array (in parent scope) and iterates through them and pass result to item prop in rad-card, but since computedResults is defined in parent component my rad-card instance doesn't have access to it?

<rad-list model="Discount" module="Discount" results="discounts">
        <rad-card :item="result" v-for="result in computedResults" :key="result.id" :model="module"></rad-card>
    </rad-list>

I get following error:

[Vue warn]: Property or method "computedResults" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

My rad-list component:

<template>
<div class="RADlist_maincontainer">
    <layout-pagination-1 v-show="pagination.last_page > 1" :pagination="pagination" @paginate="paginate({ page:pagination.current_page, paginate:paginate })"></layout-pagination-1>
    <div class="RADlist_wrapper">
        <!--rad-card, or any other component which will use computedResults GOES HERE-->
        <slot></slot>
    </div>
    <layout-pagination-1 v-show="pagination.last_page > 1" :pagination="pagination" @paginate="paginate({ page:pagination.current_page, paginate:paginate })"></layout-pagination-1>
</div>
</template>
