it depend upon the figure.only the can it be said that whether 9 lines can be made form 4 points.
To determine the types of lines that pass through the given points, we can find their slopes. The slope between points (1, 2) and (9, 9) is (9 - 2) / (9 - 1) = 7/8, while the slope between (0, 12) and (7, 4) is (4 - 12) / (7 - 0) = -8/7. Since the slopes are different, the lines passing through these pairs of points are not parallel and represent two distinct linear equations on the grid.
THe maximum number of lines that can be achieved between 9 points is 8+7+6+5+4+3+2+1=36.

Groups are 11, 12, 1, 2; 3, 4, 9 and 10; 5, 6, 7 and 8 so you draw your lines: from between 2 and 3 to between 10 and 11 and from between 4 and 5 to between 8 and 9.
I get 9 triangle with fewer than 9 lines. Draw a square: ABCD (4 lines) Draw the diagonals AC, BD (2 lines) which meet at X in the centre. On a separate part of the page, draw triangle PQR (3 lines). That is 4 + 2 + 3 = 9 lines. The triangles are: ABC, BCD, CDA, DAB, AXB, BXC, CXD, DXA, and PQR 9 triangles with 9 lines. Could have done 13 triangles with 7 lines by drawing a line from A to BC.

T E N (count the lines: 2 in T, 4 in E, and 3 in N = 9 lines)
They are intersecting lines.

Draw a clock face. Draw lines between 12:00 to 5:00, 4:00 to 9:00 and 1:00 to 8:00.

draw lines and connect them
I'll do my best to illustrate it here * * • • • • • * • • * Start at the top left star, and draw a line to the bottom right star. Then go to the star all the way above that one. Draw a diagonal to the bottom left star, and draw a line left until you get to the center bottom dot. Tada!
