Use the graph of triangle FGH . What are the coordinates of FGH reflected across the y-axis?
Question content area bottom left
FGH has the coordinates
F=(-7,-2)
G=(9,9)
H=(7,-3)
To find the coordinates of FGH reflected across the y-axis, we need to change the sign of the x-coordinates while keeping the y-coordinates the same.
So, F' will have coordinates (-(-7), -2) = (7, -2)
G' will have coordinates (-9, 9)
H' will have coordinates (-7, -3)
Therefore, the coordinates of FGH reflected across the y-axis are F'(7, -2), G'(-9, 9), and H'(-7, -3).
