Question

WILL FAN AND MEDAL!
A line segment has endpoints at (–1, 4) and (4, 1). Which reflection will produce an image with endpoints at (–4, 1) and (–1, –4)?
a reflection of the line segment across the x-axis
a reflection of the line segment across the y-axis
a reflection of the line segment across the line y = x
a reflection of the line segment across the line y = –x

Answer 1

What do you think

Answer 2

no idea.

Answer 3

Maybe c

Answer 4

What about those two is different?

Answer 5

shouldn't the last one be in a different place?

Answer 6

oops yeah, my bad.

Answer 7

i drew it on a coordinate plane off the web, i just don't know what the last two reflections look like.

Answer 8

Let's start with x in (x,y). so -1 and -4.

Answer 9

-1 and -4 as well as 4 and -1.

(-1, y) and (-4, y)
(4, y) and (-1, y)

Answer 10

How did 4 go over to -1?

Answer 11

it went across the y axis?

Answer 12

Correct, but -1 did not cross the y-axis to become -4. Therefore, we can eliminate that it crossed the x and y axis.

Answer 13

so, it's not a or b?

Answer 14

yup

Answer 15

is it C?

Answer 16

I'm going with D.

Answer 17

Then i'll go with that. Thank you.
