Linear transformation 2D

Hi,
I have two vectors for x and y coordinates. x = [-2, -1, 1]; and y = [-3, 0, 1]. the black dots are position values recorded. All the x coordiates are in one direction (all to the right; more positive as time goes on).
I would like to make it into 1 dimensional and I think I have to use linear transformation. May I know if linear transformation is correct to be used? and also is there any built in function or examples of linear transformation of Matlab? Sorry if my question is quite general and might not be related to Matlab directly? thanks in advance!

Take the mean of all the coordinates.....make the line parallel tolong axes pass through the mean of (x,y)...will it work ?

Before you ask questions, just have a look at your problem, plot your data. Are your points on a 1-D line? If they are not on a line, then you have to ask yourself if your current question makes sense. If that is the case you should have a think about more specifically what you want to achieve. Do you for example want a plot of how long distance your animal have traveled as a function of "time" (or whatever your loging-points refer to)
