Consider any point P(x, y) in the coordinate axis.
The reflection of this point across the y-axis is the point P'(-x, y).
(x, y) and (-x, y) are the 'mirror' images of each other, with the y'axis as the 'mirror'.
For example the coordinates of the image of P(4, 13) after the reflection across the y-axis is P'(-4, 13)
or, if P(-5, -9), then P'(5, -9)
Answer: if coordinates of V are (h, k), coordinates of V' are (-h, k)
Answer: x=2

have a good day! :)
plz give me brainliest
Answer: -13
Step-by-step explanation:
= 4*(1/4) - 8(2-1/4)
= 1-8(7/4)
= 1-14
= -13
Answer:
x= -18
Step-by-step explanation:
We want to isolate x ( move everything to the other side of the equation)
-7 = -1 + x/3
-6 = x/3
x= 3*-6
x= -18
B.6 would be the right answer because thats the ratebin which it drops
