Question

The equation y = 14x represents the number of pages Printer A can print over time, where y is the number of pages and x is time in minutes. The table shows the number of pages Printer B can print over time. How many pages does each printer print per minute, and which printer prints at a faster rate? Printer A: pages per minute Printer B: pages per minute The printer that prints at a faster rate is Printer . (Type A for Printer A or B for Printer B) Printer B Time (min) 3 5 8 12 Pages printed 48 80 128 192

Answer 1

printer A :
y = 14x......14 pgs per minute

printer B :
(3,48)(5,80)
slope = (80 - 48) / (5 - 3) = 32/2 = 16 pgs per minute

printer B prints at a faster rate
