The figure is being reflected over the x axis (horizontal axis). Any y coordinate that is negative becomes positive, and vice versa. The x coordinate stays the same.
If we have some point (x,y) as the original point, then it would turn into (x,-y). Note how the y coordinate has a negative on it now.
So we can say
which is what choice C is saying.
Choice C is the answer
Choice D is NOT the answer because the words "y axis" under the 'r' should be "x axis" instead.

Answer:
B(7 , 4)
Step-by-step explanation:
(x₁ , y₁) = A(-2 , -7)
(x₂ , y₂) = Point B
Midpoint(5.5, -1.5)
Compare x-coordinates & y-coordinates
-2+ x₂ = 2.5*2 ; -7+ y₂ = -1.5*2
-2+ x₂ = 5 ; -7 +y₂ = -3
x₂ = 5 +2 ; y₂ = -3 + 7
x₂ = 7 ; y₂ = 4
B(7 , 4)
