As you travel down on the y-axis, the numbers get A.)smaller or B.)larger?

The correct answer is 'A', as you travel down a Y axis, the numbers get smaller and vice versa. Each number on the y-axis is greater than the one below it.

A coordinate system is a two-dimensional number line, for example, two perpendicular number lines or axes.

typical coordinate system via kwout

The horizontal axis is called the x-axis and the vertical axis is called the y-axis.

The center of the coordinate system (where the lines intersect) is called the origin. The axes intersect when both x and y are zero. The coordinates of the origin are (0, 0).
