Question 2: Here are some transformation rules. For each rule, describe whether the transformation is a rigid transformation (rotation, reflection or translation), a non-rigid
transformation (dilation), or neither.
1. (20, y) + (1 - 2,5 - 3)
2. (x, y) (2x, 39)
3. (x, y) → (38,3y)
4. (2,y) → (2 – 3,4)

1.
2.
3.
4.

9514 1404 393

Step-by-step explanation:

The transformations of 1 and 4 are translations (1 and 4) and reflection (4), so are rigid transformations.

The transformation of 3 is a dilation by a factor of 3, so is non-rigid.

The transformation of 2 is a horizontal stretch by a factor of 2 and a vertical stretch by a factor of 3. It, too, is a non-rigid transformation, but is not strictly dilation.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

y -5 = (-1/4)(x + 8)
