Question

Quadrilateral ABCD has vertices at A(-2,-1) . B (-4,-7) C(-9,-3) D(-8,-6) . It is reflected across the x-axis. What are the new coordinates? Explain.

Answer 1

Any point that is reflected across the x axis will have the y coordinate change sign

So for example, (1,2) reflects over to (1,-2)

Answer 2

The first thing to do is draw it out.

Answer 3

@jim_thompson5910 I think you flipped it over the y axis, not x. So all the coordinates should land in quadrant 2. Which means, @amberose10, all the x axis is still negative, but the y is positive. For example. Point A was originally (-2, -1) but now it's (-2, 1)

Answer 4

No i did the x-axis

Answer 5

Oh your numbers are different. That's why... Never mind :)

Answer 6

that's ok

Answer 7

okay.

Answer 8

amberose10 do you see how we're getting all this?

Answer 9

All the points will land in quadrant 2 if you reflect it over the x axis, so x stays as negative and y is positive

Answer 10

A(-2,1) . B (-4,7) C(-9,3) D(-8,6) Like this...

Answer 11

is that the awsner ?

Answer 12

yes

Answer 13

Studybug123 flipped all the signs of the y coordinates to get that

Answer 14

Yes :)
