Which two transformations are applied to pentagon ABCDE to create A'B'C'D'E'?
Translated according to the rule (x, y) →(x + 7, y + 1) and reflected across the x-axis
Translated according to the rule (x, y) →(x + 1, y + 7) and reflected across the x-axis
Translated according to the rule (x, y) →(x + 7, y + 1) and reflected across the y-axis
Translated according to the rule (x, y) →(x + 1, y + 7) and reflected across the y-axis

Answer 8

you can test each choice
pick on of the points. which one do you want to use ?

Answer 9

point a

Answer 10

what is the (x,y) for point A?

Answer 11

for which one

Answer 12

we are going to test the first choice

to do that we need to pick a point in the figure. Point A is ok
we need its x and y

Answer 13

-4,-2

Answer 14

next we do the translate
Translated according to the rule (x, y) →(x + 7, y + 1)

that says, add 7 to the x and 1 to the y to get a new (x,y)
what do you get ?

Answer 15

(-3+7,-2+1)
(4,-1)

Answer 16

you did that almost ok. but the point is
-4,-2 (not -3,-2)
so you should redo that.

then reflected across the x-axis
that means multiply the y value by -1
but keep the same x

Answer 17

@A.S.L.

Answer 18

(-3+7,-2+1) <----- why are you doing -3 when A is (-4,-2)

Answer 19
