Vectors starting at different origins

I'm trying to determine the projected value for a new vector based on 3 vectors starting at different origins. This is in a 2D plane not 3D. Hope someone can help with a formula.

For example:

Vector 1: (100, 100) - (300, 300)
Vector 2: (100, 150) - (300, 300)
Vector 3: (100, 175) - (300, 300)

So the y value for the composite vector end point at say point (301, yyyy) would be???


Thanks

I'm not sure what you're after. Are you trying to find the resultant of the 3 vectors?

Thanks for responding nishantp

I'm trying to find the NET or COMPOSITE result for the three vectors unless I'm not using the correct verbage. In other words, once the 3 vectors go past the point where they converge at xaxis pixel 300, the net effect of the three vectors (a single y value of the three forces at xaxis pixel 301) would be???
