Question

Will fan & medal!!

Can someone please check my work?

Answer 1

The first question is..
Find the horizontal change and the vertical change for the translation
P(4, –4) (–4, 7).

(1 point)
right 8; up 11
left 8; down 11
right 8; down 11
left 8; up 11 <—this one?

Answer 2

yes

Answer 3

Next one,
The point C(3, –1) is translated to the left 4 units and up 1 unit.
a. Write a rule to describe the translation.

b. What are the coordinates of the image point?

(1 point)
(x, y) -- (x + 4, y +1); (7, –2)
(x, y) -- (x – 4, y – 1); (–1, 0)
(x, y) -- (x + 4, y – 1); (7, 0)
(x, y) -- (x – 4, y + 1); (–1, 0) <—this one?

Answer 4

yes

Answer 5

next,
How many lines of symmetry does an octagon have? If there are no lines of symmetry, write none.

(1 point)
none
8 <—this one?
4
16

Answer 6

Answer 10

pretty sure

Answer 11

everything looks okay to me!! you won't need my help (:

Answer 12

thanks @Daltonw c:

Answer 13

The vertices of ΔABC are A(2, –5), B(–3, 5), and C(3, –3). The triangle is reflected over the x-axis. Use arrow notation to describe the original triangle and its reflection. (1 point)
A(2, –5), B(–3, 5), C(3, –3) (2, –5), (–3, 5), (3, –3)
A(2, –5), B(–3, 5), C(3, –3) (–2, 5), (3, –5), (–3, 3)
A(2, –5), B(–3, 5), C(3, –3) (–2, –5), (3, 5), (–3, –3)
A(2, –5), B(–3, 5), C(3, –3) (2, 5), (–3, –5), (3, 3) <—this one?

Answer 14

How about this one, too?
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) <—this one?
