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.

Yes. It can be done with as little as three, but you have to use your imagination. I assume you are talking about a 3 x 3 arrangement as in a tic tac toe grid. If you number them upper left to lower right,

o o o

o o o

o o o

1 2 3

4 5 6

7 8 9

Four lines: 1 to past 7, then though 8 and past 6, then through 3,2 and stop at 1, then though 5 and 9. The key is extending the lines past the grid.

Three lines: 7 through 4 and 1 at an angle. Extend the line until you can come down through 2, 5, and 8. Extend the line again until you can upswing through 9, 6 and 3. It will look like the letter N. As long as the dots are not points, this works.
