Question

DOUBLE CHECK PLEASE

Pentagon ABCDE and pentagon A'B'C'D'E' are shown on the coordinate plane below:


Which two transformations are applied to pentagon ABCDE to create A'B'C'D'E'?

A. Translated according to the rule (x, y) →(x + 7, y + 1) and reflected across the x-axis

B. Translated according to the rule (x, y) →(x + 1, y + 7) and reflected across the x-axis

C. Translated according to the rule (x, y) →(x + 7, y + 1) and reflected across the y-axis

D. Translated according to the rule (x, y) →(x + 1, y + 7) and reflected across the y-axis

Answer 1

@3mar

Answer 2

i chose c

Answer 3

First of all, reflection across the y-axis is excluded, as point A would be at the top of the pentagon if it was reflected across the y-axis.

Answer 4

so its A then?

Answer 5

@3mar

Answer 6

So we have choices a and b only.

Answer 7

It's A

Answer 8

I got it its A im pretty sure

Answer 9

Yep

Answer 10

Yes, it is the first choice as the point A has been translated 7 positive units (to the right) plus one positive unit upward. After that it has been reflected across the x-axis.

Answer 11

Thanks for the medal!
