Question

Write a translation rule that maps point D(7, −3) onto point D'(2, 5)

I need major help, please???

Answer 1

x' - x = 2 - 7 = - 5

y' - y = 5 - ( - 3 ) = 5 + 3 = 8

( x , y ) -->( x - 5 , y + 8 )

Answer 2

i don't understand

Answer 3

Let's look at the x-coordinates, paying attention to signs:

xD = 7 at the start point, xD' = 2 at translated point.

Relation is needed to operate on 7 to get 2 is:

You must subtract 5

Let's look at the y-coordinates, paying attention to the sign:

yD = - 3 at the start point, yD' = 5 at translated point.

Relation is needed to operate on -3 to get 5 is:

You must add 8

Now take both equation and rewrite as an ordered pair:

( x - 5, y + 8 )...applicable only to all points in a figure "sliding" same direction.

Do you understand now?
