If the coordinate is reflected over the y-axis, the resulting coordinate of the preimage is (2, -9), (-7, -4), and (-9, -7)
Reflection of coordinate over the y-axis
When the coordinate (x, y) is reflected over the y-axis, the resulting coordinate is (-x, y)
For the triangle shown, the coordinates are (-2, -9), (7, -4), and (9, -7)
If the coordinate is reflected over the y-axis, the resulting coordinate of the preimage is (2, -9), (-7, -4), and (-9, -7)
Plot the resulting coordinate points as shown:
