Question

Help Pleasee

The point A(-2, 3) is translated using T: (x, y) → (x+4, y+2).

What is the distance from A to A'?


sqrt6
2sqrt2
5
2sqrt5

Answer 1

Use the rule T: (x, y) → (x+4, y+2) to go from (-2,3) to (-2+4,3+2) = (2,5)

So the rule T: (x, y) → (x+4, y+2) takes you from (-2,3) to (2,5)

Answer 2

Now use the distance formula

d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

to find the distance between (-2,3) and (2,5)

Answer 3

tell me what you get

Answer 4

I got 2sqrt5
