Answer:
MNO was dilated by a scale factor of 2 from the origin, then reflected over the y-axis to form PQR.
Explanation:
Take the coordinate of triangle MNO, multiply x and y axis by 2:
(2, 4) * 2 = (4, 8)
(5, 4) * 2 = (10 ,8)
(6, 2) * 2 = (12, 4)
We reflect the new coordinate by y-axis:
The formula is (-x , y)
(4, 8) → (-4, 8)
(10 ,8) → (-10, 8)
(12, 4) → (-12, 4)
This coordinate is exactly the same as PQR is showing in the chart.
