Answer:
a) (4,5)
b) (0,-3)
Step-by-step explanation:
We have to perform the following reflection over given ordered pair.
a) Reflect the ordered pair (-4,5) across the y-axis
Reflection over y-axis:
[tex]r: (x,y)\rightarrow (-x,y)[/tex]
Thus, (-4,5) will be reflected over y-axis as
[tex]r: (-4,5)\rightarrow (-(-4),5) = (4.5)[/tex]
b) Reflect the ordered pair (0,3) across the y-axis
Reflection over x-axis:
[tex]r: (x,y)\rightarrow (x,-y)[/tex]
Thus, (0,3) will be reflected over x-axis as
[tex]r: (0,3)\rightarrow (0,-(3)) = (0,-3)[/tex]
