Answer:Note:
y-axis
Explanations:
When a figure is reflected about any axis, the coordinate of that axis still remains the same, but the coordinate of the other axis is negated
For example:
If the point A(x, y) is reflected about the x-axis, the reflected image becomes A' (x, -y)
If the point A(x, y) is reflected about the y axis, the reflected image becomes A'(-x, y)
In this exercise, the point F(10, -5), after reflection, becomes F' (-10, -5)
Since the y-axis still remains -5 after reflection, this means that the point F was reflected across the y-axis.
