Question

A quadrilateral WXYZ is graphed on a coordinate plane with labeled vertices.
A four-sided figure WXYZ
is shown on the coordinate plane. The figure is then reflected across the y
-axis. Which point of the figure above will end up in Quadrant I?

(1 point)
Responses

Point Y
Point upper Y

Point Z
Point upper Z

Point W
Point upper W

Point X

Answer 1

I can’t see the graph — could you either upload the picture or give the coordinates of W, X, Y, Z?

Quick rule you can use: reflecting across the y-axis sends (x,y) → (−x,y). So a point will land in Quadrant I (x>0, y>0) after the reflection exactly when it started in Quadrant II (x<0, y>0). Find which labeled vertex has a negative x-coordinate and a positive y-coordinate — that is the one that will end up in Quadrant I.
