Find the x and y coordinates. 5x + 4y = 1 and y = 1 - x

After applying the composition r0.90 ry to rs what are the coordinates of r' and s'? a. r'(–3, 1),  s'(–3, 5)b. r'(–1, 3),  s'(–5, 3)c. r'(1, 3),  s'(5, 3)d. r'(5, 3),  s'(1, 3)

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)
