100 points and brainliest to the first correct answer
I've done the work but I need to know what my new coordinates will be

Here's the question
Use the mapping (x+3, y-5), for the transformation of triangle ABC with vertices A(-2, -4), B(0, 0), and C(1, -3), find the coordinates of the new triangle A’B’C’ . You must show all your work.

And then here is the answer:
You’re going to go left side three points and down five for every point on the graph (ABC) and once you do that label the ABC marks with an apostrophe like so; A’B’C’ for every time you change places

Answer:

  • A'(1, -9), B'(3, -5), C'(4, -8)

Step-by-step explanation:

Use the given rule and find the coordinates as follows:

  • (x, y) → (x + 3, y - 5)
  • A(-2, -4) → A'(-2 + 3, -4 - 5) = A'(1, -9)
  • B(0, 0) → B'(0 + 3, 0 - 5) = B'(3, -5)
  • C(1, -3) → C'(1 + 3, -3 - 5) = C'(4, - 8)

The points are plotted, see the attached.

Answer:

Before I start, wouldn't you go right three times since it's x + 3 not x - 3. Id.k maybe I'm just slow.

Anyways, take your current points which are A(-2,-4), B(0,0), and C(1,-3) and apply the new mapping rule to them. For example: (-2 + 3, -4 -5), and that will give you A' (1,-9). If you do the same to the other two, you'd have B' (3,-5) and C' (4,-8).

I graphed A, B, C, and A', B', C' above for you.⤴⤴

Hope the graph makes sense, good luck :)
