Suppose a line segment has endpoints A(4,-5) and R(-3,9). The line is reflected over the x- axis. What are the coordinates of R'

enot [183]

Answer:

Step-by-step explanation:

We really don't care about $A'$ because it's not something the question wants, so let's just focus on $R$ .

$R$ reflected across the $x$ -axis is the same as flipping the sign of the $y$ coordinate. So, $R'=(-3, -(9))=(-3, -9)$ .

So, the answer is $\boxed{D}$ and we're done!
