Answer:
y=x/2+5/2
Step-by-step explanation:
4=1/2(3)+5/2
y=×/2+5/2
1. The rule (x, y) →(x-1, y+2) means that every point of the original figure, must be shifted 1 unit left, and 2 units up. Check the picture.
2. The rule (x, y)→ (x, -y) means that every point of the original figure is reflected with respect to the x-axis.
A(7, 4) becomes A'(7, -4)
B(6, 8) becomes B'(6, -8)
C(2, 3) becomes C'(2, -3)
3.
The transformations are: 1 translation
2 units right, followed by a
reflection across the y-axis.

Answer:
3x + y = 21
x = 2.5
7.5 + y = 21
y = 13.5
