Question

Write the coordinates for L'M'N' and then graph both the pre-image and the image.

a) L'M'N' (-9,9), (9,18), (9,-9)
b) L'M'N' (-3,3), (3,6), (3,-3)
c) L'M'N' (-1,1), (1,2), (1,-1)
d) L'M'N' (-6,6), (6,12), (6,-6)

Answer 1

For the following coordinates:

• Transformation A: Pre-image scaled by 3.
• Transformation B: Pre-image scaled by 2.
• Transformation C: No scaling (factor 1).
• Transformation D: Pre-image scaled by 2.

How to graph coordinates?

For L'M'N' (-9,9), (9,18), (9,-9), the scale factor seems to be 3, as the x and y values are tripled compared to what would be the original points.

For L'M'N' (-3,3), (3,6), (3,-3), the scale factor seems to be 2, as the x and y values are doubled.

For L'M'N' (-1,1), (1,2), (1,-1), the scale factor seems to be 1. This set of points appears to be unchanged, suggesting either no transformation or a scale factor of 1.

For L'M'N' (-6,6), (6,12), (6,-6), the scale factor seems to be 2, similar to the second set.

Transformation A: The pre-image points are scaled by a factor of 3 to get the image points.

Transformation B: The pre-image points are scaled by a factor of 2.

Transformation C: The scale factor is 1, indicating no change in the size of the triangle.

Transformation D: The pre-image points are also scaled by a factor of 2.
