You need distance from B to C and A to C. You have created a triangle from a straight line. Correction of B to line up between A and C would be trigonometry based. Answer would obviously be slightly less than 1/8 inch in same left direction you moved A.
Or you could just blame Bush.

Here is Mikiec's triangle; it's trickier than you might think and he's just having fun with you. During the off-season, he's guest lecturer at M.I.T. on this stuff....

[Bernica]

This is why I have been looking for someone to explain compound curves in "carpenter terms". If he is at MIT, then he know Catia and beyond. Back to my tape measure.

[Danr55]

Patrick,who are you trying to fool? Mikie can't. even spell.MIT!

[mikiec]

Actually, I did take a couple of classes at MIT.

[Danr55]

Oops. I guess I was wrong. He can spell MIT.

[Car Nut]

Now that we are done playing, the answer should be obvious. The answer is you don't have to move squat. You can always draw a straight line between two points no matter where you place them. Mikie does not put any qualifications on this line.

[Paul F]

You're assuming that the line is running left to right. What if it is running up and down?

[Car Nut]

The question was very simple. " How much do I have to move point B to maintain a straight line to point C?".

Mikie has sucked us all into thinking it is complicated, when it is truly not.

[Danr55]

Did you see my question about adjusting iron sights. That sounds like an adjusting iron sights question. In which case it does matter how far it is from A - C and how far it is from A - B.

If I move point A 1/8" to the left. How much do I have to move point B to maintain a straight line to point C?

As said above, there is always a straight line between only two points. As put my Mikie, the question is about moving B to maintain a straight line to C, which would tell me that he is only asking about these two points. He does not say "through C", he says "to C". If that is true, then it doesn't matter where A gets moved to. Just taking a shot!

Agreed.

Where do you see anything at all in his question that substantiates that. You are overthinking and making assumptions the text does not give you.

[mikiec]

Dan, I know how to adjust iron sights.

[mikiec]

OK,

Let's change this a little bit. Point C does not move. I'll give it a distance say 10 feet. Ig point A is moved 1/8 inch how much does point B need to move to keep the straight line?

Professor Erwin Corey asked this.

[Danr55]

Point B will move .10274 inches in the same direction as A.

Still not clear. Changing from 26" to 10 feet? I don't think that matters. And, you also don't state if you are solving the straight line "to" C or "through" C from A to B. Otherwise, sounds like my previous answer would stand.
Assumptions:
A to B are a straight line (doesn't matter how far apart)
C is somewhere in space (no statement that it resides in the same straight AB line, only in a fixed point, which could be miles away!)

[Danr55]

Bernie, Try with ABC being a straight line. A being moved out of line 1/8" creating lines AC and BC. The issue is to solve for the distance from point B to line AC as the short leg of a triangle.

Line ABC=120"
Line AB = 26"
Line BC = 94"
Point A moves in an arc with Point C at the center, .125"
Solve for the distance from B to line AC.

Dang Dan, give 'em a hint. Tell them that the shortest distance from point B to line AC will be a line that is perpendicular to AC. Now you've got a right triangle with this newly created line being the side you're trying to solve. AB is the hypotenuse. Now that's a pretty good hint.
