Step-by-step 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://tex.z-dn.net/?f=%28-1%2C-8%29%3D%5B-1%2C-%28-8%29%5D%3D%28-1%2C8%29)
Now next transformation is dilation with a factor 4.
If we do dilation with a factor  to the point
 to the point 
New co-ordinates after dilation became 
So,
