Answer:
8.3 L/s
Step-by-step explanation:
To find the answer you need to find the slope also known as the rate of change. When you find slope it is always change in y over change in x.

Then simplify

Then divide to get your slope/average rate of change
= 8.3
Rewrite and factor 9 and 21;
3•3+3•7= 3(3+7)
GCF for 9 and 21 is 3
Answer:
