To delete an object from a slide in a presentation, you can follow these steps:
1. Click on the object you want to delete to select it. You will see handles around the object indicating that it is selected.
2. Press the Delete key on your keyboard. This will remove the selected object from the slide.
Alternatively, you can right-click on the object and select "Delete" from the context menu that appears.
If you want to delete multiple objects at once, you can hold down the Shift key on your keyboard while clicking on each object to select them all, and then press the Delete key to remove them from the slide.
