Question

The point (–7, 1) when reflected across the origin maps ontoQuestion 1 options:A) (7, –1).B) (7, 1).C) (–1, 7).D) (1, –7).

Answer 1

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.
