MARKING BRAINLIST QUESTION BELOW PLSSSSS PLSSSS HELP

Answer 1

Answer:

1. 75 feet per hour

2. $\frac{15}{7}$ pounds per year

Step-by-step explanation:

The rate of change can be represented as the slope of the equation.

The slope of any relationship is rise over run.

In number 1, we can see that the climber gained 300 feet in 4 hours. This means that the rate of change will be $300\div4=75$ feet per hour.

In number 2, we can see that the teacher gained 45 pounds in a timeframe of 21 years. This means that the slope is $\frac{45}{21}$, which can be simplified down to $\frac{15}{7}$l

Hope this helped!
