How do you write an equation for a vertical line on a graph?
The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept . (link) For instance in the graph below, the vertical line has the equation x = 2 As you can see in the picture below, the line goes straight up and down at x = 2.
How to add straight lines to a plot in R?
abline() function in R Language is used to add one or more straight lines to a graph. The abline() function can be used to add vertical, horizontal or regression lines to plot. Syntax: abline(a=NULL, b=NULL, h=NULL, v=NULL, …) Parameters: a, b: It specifies the intercept and the slope of the line h: specifies y-value for horizontal line(s)
How to add vertical lines to a plot?

How to add a marker to a plot in Matplotlib?
Here x1=25, x2=65, y1=10, y2=45. Consider the code below which adds a dashed green line from point (25,10) to (65,45) to the above scatter plot. You can also add the marker if needed.
How to draw an arbitrary line in Matplotlib?
Now lets us draw an arbitrary line through this line. We can do this directly by providing the corresponding boundary range in the plot function of the matplotlib. We can also set the formatting options like color, line width, line style, marker style, marker width, etc.
