Question

Parallelogram abcd has vertex coordinates A (-4, 4), B (-1, 4), C (-2, 2), D (-5,2). it is reflected across the y- axis. what are the coordinates of A?
A. (-4, 4), B. (4, -4), C. (-4, −4), D. (-5, 2)
plz help anyone

Answer 1

When reflecting: 
x axis: (x,y) becomes (x, -y)....x never changes 
y axis: (x,y) becomes (-x,y).....y never changes 

so...
point a: (-4,4) becomes (4,4)
