Answer: Point E
Explanation:
The least y-coordinate is the smallest y value. The y-axis is what let's the point travel up and down. If the point goes higher, the y-coordinate is more positive. If the point goes lower, the y-coordinate is more negative.
To find the least y-coordinate, we want to find the point that is the lowest of them all. Point E is the lowest point. Therefore, Point E is the answer.
