<u>ANSWER TO PART A</u>
The given triangle has vertices
The mapping for rotation through counterclockwise has the mapping
Therefore
We plot all this point and connect them with straight lines.
ANSWER TO PART B
For a reflection across the y-axis we negate the x coordinates.
The mapping is
Therefore
We plot all this point and connect them with straight lines.

Answer:
-273
Step-by-step explanation:
find the common difference:
d = 7 - 11 = - 4
a_1 = 11
a_72 = (72 - 1)* (-4) + a_1
a_72 = (71)* (-4) + 11
a_72 = -273
