Question

Triangle ABC is transformed to form triangle A'B'C' . A is at (3, 1) , B is at (1, 8) , and C is at (7, 2) . Which transformation happened to​ ​ △ABC ​ ​to form​ ​ △A'B'C' ​​? Drag and drop the the correct answers into the each box to complete the sentence. ​ ​ △ABC ​ ​ is to form ​ ​ △A'B'C' ​ ​ . A graph with a triangle on it formed between points A begin ordered pair negative 3 comma negative 1 end ordered pair, B begin ordered pair negaive 1 comma negative 8 end ordered pair, and C begin ordered pair negative 7 comma negative 2 end ordered pair.

Answer 1

A reflection through the line y=x.

Explanation:

Comparing the pre-image and image points, we have

A(3, 1)→A'(-3, -1)

B(1, 8)→B'(-1, -8)

C(7, 2)→C'(-7, -2)

Both the x- and y-values of each point are negated.

A reflection across the x-axis will negate the y-coordinate; a reflection across the y-axis will negate the x-coordinate. Both in one transformation is the same as reflecting across the line y=x.

Answer 2

98 divided by 6 is close so the answer would be ok

Explanation:

answer IS... 981
