It could either be a graph with 3 horizontal axes;
or
a graph with one horizontal axis and two vertical ones. This would be for situations where you wish to plot several dependent variables against the same independent one, but the units or scale of the independent variables do not allow you to use the same axis. For example, you may wish to plot the rate of inflation (%) and numbers unemployed (millions) in an economy against the same independent variable, time;
or
it could be a three dimensional graph. And, by that is meant a genuine 3-d graph with 3 interacting variables rather than a graph that has been given a spurious (and sometimes misleading) third dimension.
The graph is called a corrdinate plane. The horizontal is called the x-axis. The verticle is the y-axis.
x axis
distance-time graph
Origin.
horizontal:x vertical: y
The y-axis is the vertical line on a line graph.
The graph is called a corrdinate plane. The horizontal is called the x-axis. The verticle is the y-axis.
It is called the horizontal axis.
x axis
It is the Y-axis.
distance-time graph
It is called the cartesian plane
Yes, on a graph, the horizontal axis is called the x-axis.
Y axis
in or out
The horizontal axis is the x axis and the vertical axis is the y axis
A graph with distance on the vertical axis and time on the horizontal axis is called adistance-time graph. Time is directly proportional to time because as the direction increases, so does time.
