Just connect the dots.
I can do it with 7 lines... But I cannot draw in this Wiki interface...
The Lewis Dot Diagram for Xenon (Xe) has 8 dots surrounding the element symbol, as it has 8 valence electrons in its outer shell. These dots represent the 8 valence electrons available for bonding.
To connect 9 dots with 4 lines, you must think outside the box. The key is to draw lines that extend beyond the boundaries of the dots. Start by drawing a line that goes through the first three dots in an L shape, then continue the line outside the dots to connect the remaining dots. This unconventional approach allows you to connect all 9 dots with just 4 lines.
Here are the 12 dots, labeled so we can talk about them:[1] - [ 2 ] - [ 3 ] - [ 4 ] -[5] - [ 6 ] - [ 7 ] - [ 8 ] -[9] - [10] - [11] - [12] --- Put your pencil down on #9, and don't pick it up until you're finished.-- Draw line-1 up through #5 and #1, and keep going up for a ways,just far enough so you can do the next step with a straight line.-- Draw line-2 slanting down through #2, #7, and #12.-- Draw line-3 straight to the left, through #11, #10, and back to #9.-- Draw line-4 slanting up, through #6 and #3, and keep going fora ways, until you're exactly straight up above #4.-- Draw line-5 straight down, through #4 and #8 .It all depends on the arrangement of the dots.Besides, there is nothing about straight lines, so used curved lines insteaddistribute the 12 dots around the perimeter of a pentagonSince you didn't specify the lines have to be the same length... Arrange the dots in a grid as follows :-OOOOOOOOOOOOThen - starting at he top left corner, draw a 'square spiral' (doesn't matter whether you go clockwise or anti--clockwise) - this will cover ALL the dots AND use only five lines !See Related Link below for a graphic.It all depends on the arrangement of the dots.Besides, there is nothing about straight lines, so used curved lines instead

first circle draw 2 dots. second circle draw 8 dots third circle draw 10 dots!
Okay!Here Are Your Nine Dots In Number Form:1 2 34 5 67 8 9Now, start at dot 3and draw a line through dot 5 to dot 7.Now, draw a line from dot 7 leading to dot 9, but go over dot 9.After that, draw a line joining from the end of the previous line to dot 2, but going over dot 2 to be in line with dot 1:And Last Off, Draw a line going from the previous line though to dot 7. Finished (:
The key to this (old) puzzle is to realize that the lines don't have to end on a dot, they can be extended beyond the end of the row or column.If the dots are numbered1 2 34 5 67 8 91) Start with dot #9 - draw a line through #5 to #12) From #1, draw a line through #2 to # 3 and then continue the line far enough out to be able to draw the next line3) Draw a line from the end of the previous line through # 6 and #8, ending the line under #7.4) Draw a line from the end of the previous line through # 7 and #4 back up to #1See the diagram below (it's not perfect, but you should be able to follow the idea)1===2===3===|.\ . . . . . . . . . ./| . .\ . . . . . . ./4 . . . 5 . . . 6| . . . . \ /| . . . . / \7 . . . 8 . . . 9| . . /| . /|/
Yes, you can connect 9 dots set in a three on three array with four lines by imagining the array as a square with a dot at each corner and one dot in the center. You would draw a line from the top-left dot to the bottom-right dot, another line from the top-right dot to the bottom-left dot, one line horizontally through the center dot, and one line vertically through the center dot.
If n = 4, then 2n = 8 25 + 8 = 33 25 - 8 = 17 25 x 8 = 200 25/8 = 3.125
