Answer 1

• 5
• 1.5; the origin

Explanation:

Translation

For the translation find the distance between corresponding points of A and A'. It is 5 units.

Dilation

We see the figures A' and A'' are symmetrical and the sides on the x-axis overlap. It means the center of dilation is the origin, the point (0, 0).

Find the scale factor by dividing the corresponding x- or y- coordinate of A'' to the one of A'.

Take points (-2, 0) of A' and (-3, 0) of A''.

The scale factor is:

• k = -3/-2 = 1.5
