Answer 1

first question:
we have to compute the difference between the coordinates of point D and point B.
Now we have:
D=(4,-6), and B=(-3,-8)
so what is:
4-(-3)=...?
and:
-6-(-8)=...?

Answer 2

7 2

Answer 3

ok! So our traslation vector is <7,2>

Answer 4

so what does that mean

Answer 5

a is 7,2

Answer 6

it means that starting from point B, we have to perform a traslation of 7 units to right and 2 units up, in order to get the point D

Answer 7

then e to c is -4 , -5

Answer 8

second question:
we have to compute the difference between the coordinates of point E=(-3,7) and point
C=(-7,2).
So what is:
2-7=...?
-7-(-3)=...?

Answer 9

-5 -4

Answer 10

ok!
so our traslation vector is:
<-5,-4>

Answer 11

but you have to go over -4 and down -5 so wouldnt it be -4, -5

Answer 12

yes! you are right, our traslation vector is:
<-4,-5>
