Step-by-step explanation:
The two elements that effectively support the written content on a slide are colored text and images.
Colored text can be used to highlight important information or create emphasis. It can also help differentiate between different sections or points on a slide.
Images, on the other hand, can be used to visually represent concepts, provide examples, or enhance the message being conveyed. They can make the content more engaging and easier to understand.
