Question

What are the coordinates of the image K(-8,7) after the translation?

Answer 1

As per given by the question,

There are given that the coordinates of the image is

`k(-8,\text{ 7)}`

Where, x=-8 and y=7 like, k(x, y).

Now,

There are also given that the coordinates after translation.

`(x,y)\rightarrow(x-10,\text{ y-2)}`

then,

Put x =-8 and y= 7 into the above coordinates instead of x and y.

So,

`\begin{gathered} (x,y)\rightarrow(x-10,\text{ y-2)} \\ (-8,7)\rightarrow(-8-10,\text{ 7-2)} \\ (-8,7)\rightarrow(-18,\text{ 5)} \end{gathered}`

The coordinates after translation is (-18, 5).

Hence, the option A is correct.
