Question

1) if ABC is reflected across the y axis what are the resulting coordinates for points A,B, and C

Answer 1

Answer:

A' = (-1, 6)

B' = (-2, 1).

C' = (-5, 2).

Step-by-step explanation:

Reflection  over the y-axis--->  (a, b) transforms to (-a, b).

So  A (1, 6) --->   A' (-1, 6).

Answer 2

Reflecting across the y axis means to change the sign of the x coordinate:

$(x,y)\mapsto (-x,y)$

For example, point A is (1,6), and it becomes (-1,6).

Do the same with points B and C and you'll have the coordinates of the transformed points.
