Hmm, (x,y)
x is horizontal or left right
y is vertical or up down
so
we see that A to F is move left 2 and down 5
B to G is left 2 and down 5
C to H is left 2 and down 5
so translatete ABC left 2 and down 5 and
translate FGH right 2 and up 5

<u>Answer</u>
Time taken to paint the fence by Marco and Jaylyn is 2.72 hours
Heading can be given to this is work per hour
<u>Explanation</u>
Macro 6 hours to paint fence by himself
Therefore his 1 hour work = 1/6
Jaylyn 5 hours to paint the same fence by herself
Therefore 1 hour work of Jaylyn = 1/5
Together 1 hour work = 1/6 + 1/5 = 11/30
Therefore time taken to paint the fence together by them = 30/11 = 2.72 hours
