  1. What is the slope of the line 4x - 2y = 8?

    Answer: 2

    Rewrite as y = 2x - 4, so the slope is 2.

  2. A glide reflection combines a reflection with which other transformation?

    Answer: Translation

    A glide reflection is a reflection followed by a translation along the mirror line.

  3. The midpoint of a segment is (2, 2) and one endpoint is (0, 0). The other endpoint is?

    Answer: (4, 4)

    The other endpoint is twice the midpoint minus the known endpoint: (4, 4).

  4. Under a dilation centered at the origin with factor 1/2, point (8, 4) maps to?

    Answer: (4, 2)

    Multiply each coordinate by 1/2: (4, 2).

  5. Which transformation would turn a shape into a larger, similar shape?

    Answer: Dilation with factor greater than 1

    A dilation with a scale factor greater than 1 enlarges the figure while keeping it similar.

  6. What is the slope of a vertical line?

    Answer: Undefined

    A vertical line has no horizontal change, making the slope undefined.

  7. Reflecting the point (-3, 7) across the y-axis gives?

    Answer: (3, 7)

    Reflecting across the y-axis negates the x-coordinate: (3, 7).
