3. What is the correct description for the translation of A to A'?
A(10, 3) A'(1, 6)
right 9; up 3
left 9; down 3*
right 9; down 3*
left 9; up 3
The point C(x, y) is reflected over the x-axis. Use arrow notation to describe the original point and its
reflection. (1 point)
(x, y) (x, 2y)
(x, y) (–x, y)*
(x, y) (–x, –y)
(x, y) (x, –y)
1.C
2.D

yeaaa idk how you'd get a 7/7 when theres only 6 multi questions and 2 writeing promts
your boi you have to type the last two questions do the math and type your answer in.

i makered two because i was not sure
A translation is defined as:
T: (x,y) -> (x+p,y+q)
where p and q are given constants.
For example:
(10,3) -> (10+p, 3+q) = (1,6)
10+p=1 => p=1-10=-9
3+q=6 => q=6-3=3
So we have established that the translation is
T: (x,y) -> (x-9, y+3)
(note: if p is positive, translation is to the right, if q is positive, translation is upwards)
The reflection about the x-axis is flipping the image (or point) about the x-axis, it is defined as:
Sx: (x,y) -> (x,-y)
from y to -y means it goes from above the x-axis to below the y-axis.
