Answer:

<h3>            R(-1, -9)</h3>

Step-by-step explanation:

When we reflect over x-axis then the x-coordinate doesn't change and the y-coordinate changes its sign

in means  if R = (x, y) then R' = (x, -y)

so we have:

x = -1    and      -y = 9

                        y = -9

which gives R = (-1, -9)
