Find the depth of the river at 9 hours and 18 hours by seeing where the line is on the Y axis.

At 9 hours the river is 18 feet deep

At 18 hours the river is 21 feet deep.

The average rate of change is the change in Y over the change in X

The Y is the depth and the X is the time:

(21-18) / (18-9) = 3/9 = 1/3 = 0.33

The average rate of change is 0.3 foot per hour. ( Rounded to nearest tenth)

A chess player played 20 games total. If he won 2 of the games, what is the ratio of games he lost to games he won?

So, we have useful information to answer this question. We know that he played 20 games and he won 2 games. To find the ratio of the games lost, we have to subtract the number of games played and the number of games won.
20-2=18
So now we can find the ratio of games won and games lost
The answer is 18:2, 18 to 2, or 18/2.
You can also simplify the ratio to 9:1
So the final answer is 9:1
