Answer 1

To find the coordinates of point \( B' \) after translating point \( B \) left by 27 units and down by 38 units, you can apply the following transformations to the coordinates of point \( B \).

Starting point:
\[
B = (9, 9)
\]

**Translation Left by 27:**
- To translate left, you subtract from the x-coordinate:
\[
x' = 9 - 27 = -18
\]

**Translation Down by 38:**
- To translate down, you subtract from the y-coordinate:
\[
y' = 9 - 38 = -29
\]

Now, combining these results, the new coordinates \( B' \) are:
\[
B' = (-18, -29)
\]

Thus, the coordinate points of \( B' \) are:
\[
B' = (-18, -29)
\]
