Question

The transformation T =
is applied the figure below.
What type of transformation of triangle ABC was applied by T?
rotate 180° counterclockwise about the origin
reflect across the line y = x
reflect across the line y=-x
rotate 270° counterclockwise about the origin

Answer 1

Answer:

See explanation

Step-by-step explanation:

You question is missing some necessary information.

However these are the mappings for the following transformation.

Rotate 180° counterclockwise about the origin. The mapping is

$(x,y)\to(-x,-y)$

Reflect across the line y=x.

The mapping is

$(x,y)\to(y,x)$

Reflect across the line y=-x

The mapping is:

$(x,y)\to(-y,-x)$

Rotate 270° counterclockwise about the origin. The mapping is

$(x,y)\to(-y,x)$

Answer 2

Answer:

reflect across the line y = –x (C)

Step-by-step explanation:

If you multiply the point 1,4 by the matrix you get -4, -1

it cant be 180 since that would make it -1,-4 not -4,-1.

y=x would mean its positive making it 4,1

y=-x would mean atleast -x is present and if you use other values it swaps x and y

270 would be x,-y
