Answer: See each part below.
Part A: The y-intercept is the first value, or 12. That means that they bird is 12 miles from its nest when the time started.
Part B: The average rate of change is the slope. From 1 to 3 hours, the bird went from 20 to 36 or 16 miles. 16 miles in 2 hours is the same as 8 miles in 1 hour.
Part C: To find the extent of the domain, write and solve the following equation for 172 miles.
172 = 8x + 12
160 = 8x
20 = x
The domain will go up to 20 hours.
Hope the answer helps you!!!

Answer:
Yes, they are proportional.
Step-by-step explanation:
Using this from what I found helped me answer the question, and if you compare their ratios, they are both going to show that 75% each class have texted:
Proportional: When quantities have the same relative size. In other words they have the same ratio.
All you would have to do is compare the amount of students that texted(x) to the amount of students there are total in the class(y). When you compare them in a y:x format, it will all lead up to the results showing that 75% of both groups have texted.
<span>1/8 + 2(1/2m + 5) = 1/4m + 7 would equal m=-25/6</span>
