Answer: In point-slope form it's y-2=2/3(x-1)
Since you're on a timer I didn't put a explanation if you want a explanation I can put it into this answers comment.
The standard equation of a circle with radius r and centred at (h,k) is given by:
(x-h)^2+(y-k)^2=r^2.
Substitute (h,k)=(-4,9) and r=10 to find the exact equation.
Does it tell you what the rate is that they charge per half hour? If it doesn’t I think the answer is just (x)(11). x being the rate charge per half hour, and 11 being 5.5 times 2. (This answer is for the first question)
Answer:
