Answer 1

Answer:

The reflection across the x-axis of (-85, 40) is (-85, -40).

How to reflect a point over the x-axis?

A reflection over a given axis, just translates the point to the other side of the axis, in such a way that the distance between the point and the axis does not change.

Then, for a point (x, y), a reflection across the x-axis gives the point:

(x, -y).

So only the sign of the y-component changes.

Now we can apply that to our point, the reflection across the x-axis of (-85, 40) is just (-85, -40).
