List the coordinates of S¹ in the box provided

A triangle has the following vertices: (–4, –3), (–1, –3) and (–4, –2). If the triangle is dilated with a scale factor of 3, what are the vertices of the dilated image?

• (–1, 0), (2, 0), (–1, 1)

• (–12, –9), (–3, –9), (–12, –6)

• (12, 9), (3, 9), (12, 6)

• (–7, –6), (–4, –6), (–7, –5)

∆ABC was originally located at A(9, –3), B(3, –3) and C (–6, 0). After dilation, the image coordinates of the triangle were A’(3, –1), B’(1, –1), and C’(–2, 0). What was the scale factor for the dilation?

• 3

• $\frac{1}{3}$

• 2

• –3

Point C of the triangle CDE is located at (4, 1). If triangle CDE is reflected about the y-axis, what are the new coordinates of Point C?

• (4, 1)

• (4, -1)

• (-4, 1)

• (-4, -1)
