When a point is reflected across the x-axis, the x-coordinate remains the same, while the y-coordinate changes sign.
Given the original point at the bottom of the heart is (314, 712), its reflection across the x-axis will be:
- The x-coordinate: 314 (remains the same)
- The y-coordinate: -712 (changes sign)
Thus, the coordinates of the point at the bottom of the heart in the reflected image are (314, -712).
