Number of Soda Bottles



A coordinate plane titled Number of Soda Bottles Made is shown. A horizontal axis is labeled Time (minutes) from 0 to 10. A vertical axis is labeled Number of Soda Bottles from 0 to 400. A line rises from left to right starting at the origin, (0, 0), and passes through plotted points (3, 120) and (8, 320).

Answer 1

Slope = (320 − 120) / (8 − 3) = 200 / 5 = 40.
So the machine makes 40 soda bottles per minute (y = 40x).
