- Q4What are the coordinates of the new image of the point (2, -4) after a dilation with a center of (0, 0) and scale factor of 4?(8, -16)30s
- Q5Under a dilation centered at the origin, the new image is congruent to the original image. What is the scale factor?130s
- Q6After a dilation with a center of (0, 0), a point was mapped as (1, 4) → (4, y). A student determined y to be 16. Evaluate the student's answer.the student was correct30s
- Q7What is the scale factor if Triangle A is the original figure?1.530s
- Q8After a dilation with a center of (0, 0), a point was mapped as (4, -6) → (12, y). A student determined y to be -2. Evaluate the student's answer.the student incorrectly divided by the scale factor instead of multiplying it30s
- Q9What is the scale factor if Triangle B is the original figure?2/330s
- Q10In a dilation with a scale factor of 3/4, the new image is __________ the original image.smaller than30s
- Q11When given an (x,y) coordinate and scale factor, how is the prime coordinate calculated?Multiply coordinate by scale factor30s
- Q12If the scale factor is 2.2, is the dilation and enlargement or a reduction?Enlargement30s
- Q13in a dilation, the fixed point about which the figure is enlarged or reducedCenter of Dilation30s
