Given the point:


\mleft(-7,1\mright)

You know that it must be reflected across the Origin.

Then, it is important to remember that the rule for this type of translation is the following:


(x,y)\rightarrow\mleft(-x,-y\mright)

Therefore, knowing this rule, you can find the Image of the point given in the exercise by applying it:


(-7,1)\rightarrow(7,-1)

Hence, the answer is: Option A.
