for the first, you want a line segment connecting the origin to the point (8,2)

for the second, you want a line segment connecting the point (8,2) to the point (1,4)

for the third, you want a line segment connecting the point (1,4) to the point (0.5, 3.5)

can you continue?

(of course, if you wish, you could make the lower-center pocket the origin, whatever)

I think I can create a formula for you. Then you can use it to create a computer program.

What makes you think he was being sarcastic? There is no function for what you are looking for. What you need is a program that will take care of what the cue is doing when it runs into a boundary.

His answer and offer seem fairly direct to me.
