Organize these options into the right categories. What could the coordinates be if they were reflected on each axis.

Groups:

(a) x-axis

,

(b) y-axis

(x,y)→(x,−y)\left(x,y\right)\rightarrow\left(x,-y\right)  

(−2,−3)→(−2,3)\left(-2,-3\right)\rightarrow\left(-2,3\right)  

(x,y)→(−x,y)\left(x,y\right)\rightarrow\left(-x,y\right)  

(6,5)→(6,−5)\left(6,5\right)\rightarrow\left(6,-5\right)  

(−2,−3)→(2,−3)\left(-2,-3\right)\rightarrow\left(2,-3\right)  

(6,5)→(−6,5)\left(6,5\right)\rightarrow\left(-6,5\right)
