A period on the periodic table is a horizontal row. The atoms in this row show a trend in their width, and in the amount of work needed to make them an ion, among the fe â¦ w other similarities.
A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin. The numbers on a coordinate grid are used to locate points. Each point can be identified by an ordered pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate. Ordered pairs are written in parentheses (x-coordinate, y-coordinate).
typically the y axis has numbers for the amount of stuff being measured the y axis usually starts counting at 0 and can be divided into as many equal parts as you want to in this line graph the y axis is measuring the amount of money spent on individual students for public education the most important part of your graph is the information or data it contains line graphs can present more than one group of data at a time in this graph two sets of data are presented in line graphs like the one above the x axis runs horizontally flat
