Question

The vertices of a triangle are located at the following coordinates: (4, 8), (-2, 6), and (0, -4).

If the triangle is dilated by a scale factor of 1/2, which of these does NOT represent a vertex
the image triangle?
A (0, -2)
B (2, 4)
C (3, 2)
D (-1, 3)
Y and C(11 7) which of the following statement:

Answer 1

• C. (3, 2)

-------------------------

The dilation by a scale factor of 1/2 results in dividing each coordinate of a vertex by two.

Hence the coordinates of vertices of the image are:

• (4/2, 8/2) = (2, 4), this is included as choice B;
• (-2/2, 6/2) = (-1, 3), this is included as choice D;
• (0/2, -4/2) = (0, -2), this is included as choice A.

The odd one out is option C.
