How do you graph \[x = - 4\]

Hint: Here in this question, we have to plot a graph. Usually while plotting the graph, we plot x axis versus y- axis. But here in this question we have only one variable. For this variable we have to plot the graph. Hence, we get a line which is parallel to y axis.

Complete step-by-step answer:
The graph is generally plotted x- axis versus y -axis. When we have two variables then we plot a two-dimensional graph. Here in this question, we have only one variable but this also a two-dimensional graph. Here y is not mentioned. For any value of y the x value will be the same and it is constant.
Suppose if we consider the value of y as 0 then the value of x is -4.
Suppose if we consider the value of y as +1 then the value of x is -4.
Suppose if we consider the value of y as -1 then the value of x is -4.
For any value of y either it is positive terms or the negative terms the value of x will be the same.
The graph for the given equation \[x = - 4\] is as shown below.

If we see the graph the line is parallel to the y-axis.
We don’t have a one dimensional graph, if the equation contains only one variable either its x or y we must know that for any value x or y the equation will be constant.

Note: The graph is plotted against the two axes namely X-axis and Y-axis. If we know the value of one, we can find the other by using the equation of the graph. This graph is two dimensional because they have mentioned only two axes.
