yap

OpenStudy (bass53):

what about this one

OpenStudy (bass53):

Point A(–4, 2) is reflected over the line x = 3 to create the point A'. What are the coordinates of A'?

OpenStudy (bass53):

A. (–4, –1) B. (–4, 8) C. (–1, 2) D. (10, 2)

i agrree, A.

OpenStudy (bass53):

with vertices D(2, 5), E(6, 4), and F(3, 3), is reflected across the line A student determined one of the vertices on the image to be (2, –5). Evaluate the student’s answer.

OpenStudy (bass53):

A. The student performed the reflection correctly. B. The student incorrectly reflected across over the x-axis. C. The student incorrectly reflected across the y-axis. D. The student incorrectly reflected across the line y = –x.

OpenStudy (anonymous):

c or b

OpenStudy (bass53):

ok but i got a few more

OpenStudy (anonymous):

I think C.

OpenStudy (bass53):

thanx

OpenStudy (anonymous):

best response would be great

OpenStudy (bass53):

After a reflection, segments are drawn between corresponding points on the image of a triangle and its preimage. What is the relationship between all of these segments?

OpenStudy (bass53):

A. They are the same length. B. They are parallel. C. They are perpendicular. D. No universal relationship exists.

OpenStudy (anonymous):

A? or C.

OpenStudy (bass53):

thank u

OpenStudy (anonymous):

of course

OpenStudy (bass53):

The point (2, –4) is reflected across the line y = –1. What are the coordinates of the image? A. (–5, –4) B. (–4, 2) C. (2, 2) D. (2, 4)

OpenStudy (bass53):

what about this one

OpenStudy (anonymous):

It's (-2. 4). You just swap the coordinates.

OpenStudy (bass53):

ok thnx cece

OpenStudy (anonymous):

yup

OpenStudy (bass53):

ok im done for right now u guys
