Answer and Step-by-step explanation:
Charlotte reads 4 books each week
b = number of books she reads each week
w = number of weeks that she reads
The number of books depends on the number of weeks, so
independent variable: w
dependent variable: b
b = 4w
╔═══╦═════════╦════╗
║ w ║ b = 4w ║ b ║
╠═══╬═════════╬════╣
║ 0 ║ b = 4*0 ║ 0 ║
╠═══╬═════════╬════╣
║ 1 ║ b = 4*1 ║ 4 ║
╠═══╬═════════╬════╣
║ 2 ║ b = 4*2 ║ 8 ║
╠═══╬═════════╬════╣
║ 3 ║ b = 4*3 ║ 12 ║
╠═══╬═════════╬════╣
║ 4 ║ b = 4*4 ║ 16 ║
╠═══╬═════════╬════╣
║ 5 ║ b = 4*5 ║ 20 ║
