Questions & Answers
Q: What are the two points defining the quadrilateral in the video?
The two points are (0, 9) and (3, 4).
Q: How is the line y = 3  x related to the reflection of the quadrilateral?
The quadrilateral is left unchanged after reflection over the line y = 3  x.
Q: How can we determine the other two vertices of the quadrilateral?
By reflecting the given vertices across the line y = 3  x, we find the additional vertices.
Q: What is the final classification of the quadrilateral?
The quadrilateral is classified as a trapezoid, as it has one pair of parallel sides.
