R.5. Define a relation < on the set of ordered pairs of real numbers (x, y) as follows: (X:V1)< (x2, V2) if and only if (1) x < x, or (2) x, = x, & y, < y2. Prove that < defines a linear ordering on the set of ordered pairs of real numbers. (This shows that the coordinate plane can be linearly ordered!)
