Jan created this 5 -point star. She used 9 lines to create this 6 -point star. How many lines join the dots in Jan's 10 -point star? (A) 35 (B) 29 (C) 28 (D) 26

Calculate total lines: For a 5-point star, Jan used 10 lines. Each point connects to 2 other points, so 5 points need 5*2=10 lines, but we count each line twice, so we divide by 2. That's 10/2=5 lines.
