In the graph below, point D is reflected across the y-axis. What are the coordinates of its image?
if all we do is reflect across the y axis; the only thing that changes is the sign of the x component
what are the coordinates for the point D?
-3 - 1 is the corret answer
cuz it flips
i cant tell what the coords of D are, my eyes aint so good anymore
but yes; the x part flips a sigh and the y parts stays the same
coordinates of D are 3, 0
(3,y) flips over the y axis to (-3,y)
im thinking C is correct
(x,-y) flips to (-x,-y) so that fits the right pattern and nothing else seems to match it :)
