Question

If a translation maps point A(-3,1) to point A'(5,5), the translation is:OA. (x+8, y + 4)OB. (x+2, y + 4)Oc. (x+2,y+6)OD. (x+8, y + 6)

Answer 1

We have the A point:

`\begin{gathered} x=-3 \\ y=1 \end{gathered}`

And the A' point:

`\begin{gathered} x^(\prime)=5 \\ y^(\prime)=5 \end{gathered}`

So:

`\begin{gathered} 5=-3+nx \\ nx=5+3=8 \\ 5=1+ny \\ ny=5-1=4 \end{gathered}`

Then, the correct answer is A:

`\begin{gathered} x+8=-3+8=5 \\ y+4=1+4=5 \end{gathered}`
