1. The problem states that Chad is planting a plant that is 4 inches tall and wants the hole to be as deep as the plant is tall. 2. We need to find the integer that represents the location of the bottom of the hole. 3. Since the plant is 4 inches tall, the hole's depth is 4 inches downward from the surface, which we represent as a negative integer because it goes below ground level. 4. Therefore, the location of the bottom of the hole is at $-4$ inches. 5. This means the bottom of the hole is 4 units below the surface, while the plant's height is 4 units above the surface. 6. So, the hole's bottom location is the negative of the plant's height, showing they are equal in magnitude but opposite in direction. Final answer: The bottom of the hole is at $-4$ inches, which is the negative of the plant's height $4$ inches.
