If FG = 2 units, FI = 7 units, and HI = 1 unit, what is GH?

GH = 4 units 

Explain :

(x, y)→(x − 9, y − 3)

Step-by-step explanation:

We have given Hexagon DEFGHI is translated on the coordinate plane to create hexagon D'E'F'G'H'I':

We write the translation one by one:

D (3, 5)

D' (-6, 2)

that translates to: (x - 9, y - 3), because that is for passing from D to D':

(3 - 9, 5 - 3) = (-6, 2)

Now for E (7,5)

E' (-2,2)

that translates to: (x - 9, y - 3), because that is for passing from E to E':

(7 - 9, 5 - 3) = (-2, 2)

Now for F(8,2)

F' (-1, -1)

that translates to: (x - 9, y - 3), because that is for passing from F to F':

(8 - 9, 2 - 3) = (-1, -1)

therefore if it is true for D and D', E and E', F and F' then it has to be true for all others for the rule to be true, so the  rule represents the translation of hexagon DEFGHI to hexagon D'E'F'G'H'I' is (x, y)→(x − 9, y − 3)
