Answer:
The answer would be “(x, y)→(x + 7, y − 7)”.
Step-by-step explanation:
First, you should choose a point from hexagon DEFGHI. (Any point is fine, But I used point F.
“x + 7” means to the move right 7 spaces.
x is the horizontal line (goes left to right). You would move your point to the right because the number is positive.
Point F moves 7 spaces to the right and lands on coordinates (6,4). Then we move on to the second step.
“y − 7” means to move down 7 spaces.
y is the vertical line (goes up and down). You would move your point down because the number is negative.
Point F moves from where it is now (aka 6,4) and 7 spaces down.
Now your point should line up with the another point. In this case, point F is now sitting at where point F’ is.
If you chose any other point, it should go to it’s own destination.
This means
D should now be at D’
E should be at E’
G should be at G’
etc.
