What you want to do with this equation is make a triangle connecting the two points you have and count the distance (rise/run) for this you would get 6/1 !
C.
he starts 6500 ft up do that's the b in y=mx+b.
the m is -250 because that's the rate, and it's negative because he's going down.
The area of the circle is equal to the area of the polygon
Your number is 34,699 right and if anything is 5000 or over round ahead so it is 30,000
Just multiply across which is
8*5 = 40
21*16 = 336
40/336 = 5/42
This is correct answer
I hope this answer helped you!!! Thank you!!!
