For these 2 points, you can say that point 1 is at (x1, y1), and point 2 is at (x2, y2). It doesn't matter which is point 1 or point 2. What DOES matter is that you keep the x1 with the y1, and the x2 with the y2.<BR/><BR/>So, if we have a point at (1,2), and a point at (4,3), the slope of the line between them canAnonymoushttps://www.blogger.com/profile/17228027233405770851noreply@blogger.comtag:blogger.com,1999:blog-5639270444406781623.post-19629701402327426552009-02-19T08:08:00.000-08:002009-02-19T08:08:00.000-08:00When subtracting Y2 from Y1 I noticed that you did...When subtracting Y2 from Y1 I noticed that you did not use the exact numbers that correspond to these y's...you even mentioned "**Notice that I didn't use (2-7)!" Can you please explain WHEN to know to subtract a particular Y from the other Y...

Can I assume that the original (black line) formula is a piecemeal formula, which states that for the domain 0 - 6, y = 0; for the domain 6 - 10, y = 1/2x - 3, etc. You are right, the slopes will be the same for the similar segments of each line, but the equation describing that segment will have a different Anonymoushttps://www.blogger.com/profile/17228027233405770851noreply@blogger.comtag:blogger.com,1999:blog-5639270444406781623.post-27562748725644698232008-08-01T17:10:00.000-07:002008-08-01T17:10:00.000-07:00I have been reading through your blog trying to fi...I have been reading through your blog trying to figure out a graphing problem. I have been trying to use geometry and trigonometry to solve the problem, keep getting stuck and can't seem to put all the pieces together to find the solution. Am hoping maybe you or one of your readers can help point me in the right direction.<BR/><BR/>Essentially, I have polygonal chain (aka polyline) defined by aUnknownhttps://www.blogger.com/profile/04758905976888225640noreply@blogger.com
