answer part A for me and explan then im gonna post part b then part c then part d then im done (blushingbees, im gonna make a free points post just for you) because you helped me alot, thank you!

Yes, each of the proposals are represented by linear functions. Each of the proposals have a constant rate of change.

Step-by-step explanation:

For a function to be linear, it needs to have a constant rate of change. The rate of change can also be described as the change in y over the change in x.

Sarah's Proposal:

Linear functions are functions that are graphed as a straight line. As you can see, the graph of Sarah's proposal is a straight line, so this proposal must be represented by a linear function.

Gene's Proposal:

As you can see on the table, for every 5 hours worked, the amount of money raised increases by 35. This represents a constant rate of change, which means that this function must also be linear.

Paul's Proposal:

Paul's proposal is expressed as an equation, y = 10x + 7. This equation is written in the format y = mx + b, where m is the rate of change. The rate of change in Paul's proposal is 10. This means that for every 1 hour worked, the amount of money raised increases by 10. This is a constant rate of change, so this function must be linear.

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
