Question

Cassandra is creating a program and for one part she uses the following rule to move points across the screen

(x,y) → (x - 5, y + 6)
What output does the rule give when the input is (5,-6) and explain the process.

Answer 1

(0, 0 )

Explanation:

the translation rule (x, y ) → (x - 5, y + 6 ) , means

subtract 5 from the original x- coordinate

add 6 to the original y- coordinate

then

(5, - 6 ) → (5 - 5, - 6 + 6 ) → (0, 0 )
