A vertical number line
Reflection about the y-axis can do that.
18 and below
Once a graph has been created, y would be the axis which is shown up and down on the graph. The x axis is shown from left to right on the graph. Both are reference lines on a graph.
Horizontal line (left to right) is the x-axis and the vertical line (up and down) is the y-axis.
If there is one independent variable, and one or more dependent variables, then they would be plotted on the y-axis. If there are a mix of discrete and continuous variables, then the continuous variables should be plotted on the y-axis. In general, though, any variable can be plotted on the y-axis.
In a graph the vertical axis displays the y variablewhile the horizontal axis displays the x variable. The manipulated variable will be shown on the x axis while the responding variable will be shown on the y axis.
The value of the dependent variable
The dependent variable is shown on the vertical, or y-axis of a graph.

Replace each point with coordinates (x, y) by (-x, y).

It can be.
Horizontal line (left to right) is the x-axis and the vertical line (up and down) is the y-axis.
In that case, when going from left to right, the graph will slant upwards.
