Question

A triangle has vertices (-4, 1), (6,9), and (2, -3). The triangle is translated 3 units up and then rotated 90° clockwise. Which of the following will NOT be the coordinates of a vertex of the image after both transformations?

Answer 1

EXPLANATION

Let's see the facts:

A triangle has vertices of (-4, 1), (6,9), and (2, -3).

If it is translated 3 units up the coordinates of y-axis will be changed by 3 units as follows

A=(-4, 4), B=(6,12), and C=(2, 0).

Now, we can draw this triangle and consider the new coordinates of the triangle

A'= (4,4) B'= (12,-6) C'=(0,-2)

So, the coordinates C) (3,4) is not a coordinateof a vertex of the image after both transformations.
