Question

The coordinate grid below shows Triangle STU and its image after translation, Triangle S′T′U′.



Which coordinate rule represents the translation seen?

(x, y) →(x – 7, y + 3)

(x, y) →(x – 10, y + 3)

(x, y) →(x – 10, y + 2)

(x, y) →(x – 7, y + 2)

Answer 1

Your original triangle is the regular letters. The translated triangle is the letters with the '

Answer 2

Start from a point. (Let's say T)

T is at (3,1)

Now find T'

T' is at (-7,4)

Look for the distance at x

It went 10 spaces left so -10

Look for the distance for y

It went 3 up so 3

(x,y) -> (x-10, y+3)
