How to find intersection points between lines using Excel?
 

I need to find out intersection point between few (100 to be exact) parallel
lines with a another line. How could I program this using excel so that i can
view both X and Y coordinates in different column??

thanks

find the intersection of the topmost line, then it is just a matter of
adjusting for the distance between the parallel lines and the angle of
intersection.

Probably could be done with worksheet formulas, but you provide no
information.

sorry for not providing the other infor mation but i am a beginner at using
excel sheet..it would be really helpful if you could elaborate on this..what
if i need to find out intersection points between lines of different slope
with one line...
thanks

Assume the topmost or one of the 100 lines is

Y = 3X + 5

and the intersecting line is

Y = -6X - 10

then
3x + 5 = -6X - 10

9x = -15
x = -15/9
x = -3/5


substituting in to the first equation

y = 3 * (-3/5) + 5 = 0

So the equations for the parallel lines are just going to vary by the Y
intercept.

but the general form will be

x = (-5 - YIntercept)/ 9
and for y:

y = 3x - YIntercept
so
y = 3[(-5 - YIntercept)/9] + YIntercept

so you can use these to build your solutions.
