Slope function or not

[polynaux]

Hi Guys,

I have written a loop that determines in which triangle the user input lays:

Dim TotalAttr As Integer = 2
For Each item As String In CriteriaAttributeNames  
            If inputAssessment < j * (10 / TotalAttr) Then   
                inputAssessmentMembership = CriteriaAttributeNames(k).ToString         
                Exit For 
            End If
            j = +1
            k = +1
 Next item

If the if-clause is invalid it will increase j and try the next triangle which will be just next to the smaller one.
Ok that works, but if I want to determine the exact match it get hard:

I need more that just knowing ok, its the first triangle, the second i.e low or high. What I need is i.e if user input is 2 (and it is hence in the first triangle) than what is the y value (in the image above it would be 80). How do I get this 80 ?
Any suggestions ?


Many thanks,

Polynaux
