And you want the full width at half max, so you find the point to the right of x=2 where y=5, say at x=9, and the point to the left where y=5, say x=0. The full width of your signal at half its maximum value is 9-0 = 9. Wiki has a decent figure showing this.

There are several ways to define the minimum peak separation ΔM in mass spectrometry, therefore it is important to report the method used to determine mass resolution when reporting its value. The two most widely used are the peak width definition and the valley definition. In the peak width definition, the value of ΔM is the width of the peak measured at a specified fraction of the peak height, for example 0.5%, 5%, 10% or 50%.
