Answer:

Explanation:
Given points are

And given transformation is

We will start from left to right.
First transformation is reflection about x-axis.
When we reflect about x-axis

So,
![(-1,-8)=[-1,-(-8)]=(-1,8)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/8ycbq3t8dqnzbuh2il82kvluwkl6ujxrbm.png)
Now next transformation is dilation with a factor 4.
If we do dilation with a factor
to the point

New co-ordinates after dilation became

So,
