Question

PLEASE HELPP!!!!. What does this mean if the original coordinates are A(2,3) B(0,6) C(-3,0) D(1,4) and they ask write the coordinates of the image ABCD after a reflection in the line x=1 ?

Answer 1

A B C D are points. Connect the point to look at the original figure. Do that, then I will tell you what to do next.

Answer 2

Okay I just did

Answer 3

Now draw y = x line

Answer 4

done

Answer 5

cool. Now do you remember what to do if you want to reflect it over the y axis? x axis?

Answer 6

Dont you change the x or y coordinates?

Answer 7

You on the right track...

Answer 8

So I change my y coordinates to 1?

Answer 9

Well, hold on now.

If I had (x,y) and wanted to take the reflection across the y axis then it would be:

(x,-y)

Across x axis:

(-x, y)

y = x

(y, x)

x = x coordinate number

y = y coordinate number

Answer 10

So if I wanted to reflect (1,2) across the y = x line, then it would become (2,1)

Answer 11

Thank you ! I just needed a reminder. haha

Answer 12

You re welcome
