The new coordinates wil be (5,-10)
Plot (5, 10) on graph paper to understand. Imagine that point now reflecting or "flipping" over the x-axis. In this instance, it "flips the point down," moving the original point from the first quadrant to the fourth. The new y coordinate would be the "opposite" sign of the original but the x coordinate would remain unchanged. In light of this, the point is (5, -10)
The rule for reflection over the x-axis is
(x, y) → (x, - y)
Reflection over x-axis for (5,10) → (5,-10)
Coordinates are numerical lengths or angles that uniquely identify locations on two-dimensional (2D) surfaces or in three-dimensional (3D) space ( 3D ). Mathematicses, scientists, and engineers frequently employ a variety of coordinate systems.
