Question

Which set of transformations has been performed on triangle XYZ to form triangle X”Y’’Z’’?

Dilation by a scale factor of 4 followed by reflection about the x-axis
Dilation by a scale factor of 2 followed by reflection about the y-axis
Dilation by a scale factor of 4 followed by reflection about the y-axis
Dilation by a scale factor of 2 followed by reflection about the x-axis

Answer 1

Dilation by a scale factor of 2 followed by reflection about the y-axis

Explanation:

To solve this, follow Point Z (3,-2)

When it is reflected over the y axis, it turns into (-3,-2)

When you Dialate by the origin, multiply by two on your X and Y coordinate

(-3,-2) turns into (-6,-4) and we can see that Z' is at (-6,-4), therefore it is a

Dilation by a scale factor of 2 followed by reflection about the y-axis

Hope this helps!
