Question

Use arrow notation to wrote a rule for this translation. the cornites used to be a= 1,3 b= 4,5 c= 3,1 but then were shifted 1 unit to the right and 2 units down. The aigted coordinates are a= 2,1 b= 5,2 c= 4,-1
I dont understand the rule part.

Answer 1

what happens to each x and y to get from one to the other? The result is

shifted 1 unit to the right and 2 units down

So, the rule is (x,y) -> (x+1,y-2)

and I have no idea of the meanings of "cornites" and "aigted"
