Since we only answer up to 3 sub-parts, we’ll answer the first 3. Please resubmit the question and specify the other subparts (up to 3) you’d like answered.

We compare the line with f(x)=mx+b.

So, m=3

Step 2

(b) Since 3 is positive the function is increasing. And f(x) is in thousands. So f(x)=3 means 3000 dollars. And x is in hu...
