Answer:
Your question is very short and I might misunderstand it. I think you mean a Cartesian product of the set of all real numbers RR and the set consisting of one element, the number 2.
It is, by the definition of a Cartesian product, is the set of all pairs (x, 2) where x is any real number (x in RR ) and 2... is 2.
Such a set of pairs of numbers may be represented geometrically on a plane (coordinate plane). It is the set of all pairs (x, y) where y=2 and x is arbitrary.
Because there are no restrictions on x, the only restriction is y=2. This is the equation of the straight line which is parallel to the x-axis and goes through the point (0, 2). This is the answer
