Parallelogram ABCD has vertex coordinates A (-4,4), b (-1,4), c (-2,2), and d (-5,2). It is reflected across the y-axis. What are the coordinates of C?

(1,4)

So if I remember correctly if it's against the y-axis and u are trying to make a reflection, then it would be an arrow notation which is (y,-x) and do you would change A, B, C, and D coordinates into the arrow notaton
