4. Tori went to the eye doctor. He dilated her pupils to twice their normal size during the exam. If her pupils were 2 mm originally, what size were they after being dilated?

4 mm

5. Blueprints for the model of a new garage have a scale factor of 1 inch = 4 feet. If the garage is to be 18 feet long, what is the length of the model?

4.5 in

7. check answers Give the resulting coordinates if you were to reflect the point (2, 3) across the following lines.

x axis : (2, -3) y axis : (-2, 3) y = x : (3, 2) y = -x : (-2, -3)

6. A triangle has sides measuring 6, 8, and 10 cm. Using a dilation factor of 0.75, what would the measurements of a second triangle be?

- 7.5 cm - 6 cm - 4.5 cm

2. Match the points to each area.

quadrant I : A quadrant II : B quadrant III : C quadrant IV : F on the x axis : E on the y axis : D

1. Match the coordinates to the points.

A : (3, 4) B : (-1, 5) C : (-6, -7) D : (0, -5) E : (4, 0) F : (6, -3)

3. Match the points to the coordinates.

M : (-5, -5) N : (5, -1)
