The triangle pqr shown on the coordinate grid below is reflected once to map onto triangle p´q´r´.
if vertex p’ is at (7, -6), what are the coordinates of vertex r’?
a)(5, -3)
b)(3, -5)
c) (3, -2)
d)(5, -2)

you can not drow on this

step-by-step explanation:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

"a" determine whether sage found the correct quotient. show your work
