I can do it with 7 lines... But I cannot draw in this Wiki interface...
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.
a star drawn with five lines will give you 10 dots on 5 lines with only 4 dots on each line. (or) simply draw a pentagon and put a cap ( a inverted 'V') on all sides.
