Answer: 1st image: option 2
2nd image: (x, y) ==> (x+4, y-9) ==> option 4
Step-by-step explanation:
1st image: Reflection over the y-axis means that all x-coordinates are negated while the y-coordinates remain the same.
A: (2, -2) ==> A' (-2, -2)
B: (-2, 5) ==> B' (2, 5)
C: (-4, 2) ==> C' (4, 2)
Answer: option 2
A to A', B to B', C to C'
Purple to Blue
2nd image: 1st, the purple triangle moves 4 units to the right (x ==> x+4)
Then, the purple triangle moves 9 units down to become the blue triangle (y ==> y-9)
(x, y) ==> (x+4, y-9) ==> option 4
