Question 16511: How do you go about writing a relection matrix of this given scenario?
"The vertices of quadrilateral ABCD are A(-3,2) B(0,3) C(4,-4) D(-2,-2) when it is reflected over the y-axis?"
Any help at this point would be greatly appreciated.

You can put this solution on YOUR website!
Dude all you gotta do is take the all the x values, (ie...-3,0,4,-2) and times them by -1 (it's inverse).
So, The vertices of quadrilateral ABCD refected over the Y axis would have vertices A(3,2) B(0,3) C(-4,4) and D(2,-2)
I hope this answers your question.
