Determine if Set of Points is a Function: Which set of ordered pairs does not represent a function: {(−2,5),(0,−9),(8,−2),(7,4)}, {(−3,4),(−5,4),(7,−3),(2,−9)}, \{(2, -9), (-5, -1), (-6, -3), (-5, 7)\}, {(1,−8),(−9,−2),(−4,0),(4,−8)}

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
