Triangle xyz is shown on the coordinate plane below
if triangle xyz is reflected across the line y = 1 to create triangle x'y'z', what is the ordered pair of x'?

Reflected would make a mirror image.

X is located at (1 ,-3)

Since it is being reflected across the Y axis, the X value would be the same.

The Y value is 4 units below Y=1 ( the mirror line) so the new Y value would be 4 units above the mirror line ( 4+1 = 5)

This means X' would be at (1.5)

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
