Question

Please slove for 15 points! i will give u a thank you and more!

A triangle with vertices at A(-1,1), B(-2,1) and C(-1,4) is translated. The image of vertex A has coordinates at (3 ,-1). Determine the coordinates of either the image of vertex B or the image of vertex C. Show your work

Answer 1

For this case we have the following vertices:

A (-1,1) --------> A '(3, -1)

B (-2.1)

C (-1,4)

We note that the translation rule is:

(x, y) -----------> (x + 4, y-2)

Applying the translacion rule we have:

B (-2, 1) -----------> (-2 + 4, 1-2) ------> B '(2, -1)

C (-1, 4) -----------> (-1 + 4, 4-2) ---
