Question

Which series of transformations will not change the coordinates of point N in triangle LMN?

Answer 1

d

1) Examining the picture, we can locate point N at ( 2,0) and considering that the rule for Reflection

Across the y-axis

Pre-image Image

(x. y) ------------> (-x,y)

(2,0) ------------> (-2,0)

Reflecting over the x-axis

Pre-image Image

(x,y) ----------------->(x, -y)

(-2,0) ------------------(-2,0)

Testing d

Pre-image Image

(x,y) ----------------->(x, -y)

(-2,0) ------------------(-2,0)

Translating up 4 units

(-2+4,0)------------(2,0)

So the answer is d
