Answer:
The vertices of D'E'F' are (0,-7), (2,-9) and (4,-1).
Step-by-step explanation:
We are given that,
Co-ordinates of triangle DEF are D= (0,7), E= (2,9) and F= (4,1).
The triangle DEF is reflected over x-axis to form triangle D'E'F'.
Now, 'Refection over x-axis changes the co-ordinates (x,y) to (x,-y)'.
So, we get,
Co-ordinates of vertices of triangle D'E'F' are,
D' = (0,-7)
E' = (2,-9)
F' = (4,-1)
Thus, the vertices of D'E'F' are (0,-7), (2,-9) and (4,-1).
