The -3 would be where your line crosses the y-axis, so you would plot your point at -3. your slope will always be counted as rise/run, basically meaning you would count along the y-axis a certain amount of times, in this case -1, and along the x-axis a certain amount of times, here would be three. your next plot point would be (3,-4) and so on. hope this helped!
13.20254313. Pi(2.05)^2. 4.1÷2(for the radius)=2.05.Square it and multiply by Pi. a=pi(r)^2

Visual explanation in the attachment. I hope you'll understand ;)
I=prt
I=52000*0.0675*5.5=19305
So she will pay 52000+19305=71305
