Question

10. The x-axis is also known as ………​

Answer 1

Answer:

Also called axis of abscissas. (in a plane Cartesian coordinate system) the axis, usually horizontal, along which the abscissa is measured and from which the ordinate is measured.

I don't know why “Y” for the vertical axis, but the “X” axis is simple, because “X” is a cross (across), and represents the axis which goes across, from left to right/right to left. It is customary but NOT compulsory to call the Cartesian axis X and Y as it is to name some unknowns in an algebraic equation.

horizontal axis is the answer
