Answer:
see explanation
Step-by-step explanation:
the translation rule (x, y ) → (2x, y )
means multiply the x- coordinate by 2 and multiply the y- coordinate by ), so
A (- 1, - 3 ) → A' (- 2, - 1 )
B (4, - 3 ) → B' (8, - 1 )
C (4, 3 ) → C' (8, 1 )
D (- 1, 3 ) → D' (- 2, 1 )
Add buit adding a postive and negative is same as subtracting the opposite
You have to find the parameter first!
add
to both sides.
subtract 9 to both sides.
multiply 5 to both sides.
Your answer is D) z = -40
