Question

indentify the coordinates of the reflected figure across the y-axis?

Answer 1

to write coordinates you need see x firts and y late and write

the A point is

$(2,5)$

because is 2 on x and 5 on y

The B point

$(7,5)$

The C point

$(7,2)$

The D point

$(2,2)$

to reflect across Y you need to change the sign of x or the first term on the coordinate

so

A'

$(-2,5)$

B'

$(-7,5)$

C'

$(-7,2)$

D'

$(-2,2)$
