Question

What is the image point of (−1,1) after a translation right 2 units and down 1 unit?(Exlain+rules)

Answer 1

(1,0)
For x:
left is negative units
right is positive units
translations left and right effect x
-1 + 2 = 1
For y:
translations up and down effect y
down is negative units
up is positive units
1 - 1 = 0
rules:
x'= x + l
(let l represent the different of units in x between the preimage and image)
y'= y + u
(let u represent the different of units in y between the preimage and image)
Any variables work in place of l and u they are just example variables
