Which shows the image of δrst after the rotation (x, y) → (y, –x)? image a, b, c, d? (tap image above)

Consider triangle RST. It has vertices R(-2,1), S(1,3) and T(-1,7).

If the rotation has rule

(x, y) → (y, –x),

then

R', S' and T' are exactly vertices of triangle from the first diagram.

correct choice is A.

a=r

d=q

c=p

b=s

hope this !

i just took the test, the correct answer is .. 31.5 in.
