The answer will most definitely be C
I believe the correct answer is 15, because 15/8 x 15/1= 225/8 and when you simplify that you get 28 with 1/8 left over.
Use the formula slope= y-y/x-x
-10-r/-2-8= 1/10
-10-r/-10= 1/10
Multiply the denominator (-10) on both sides
-10-r= -1
Add -10 to both sides
-r= 9
r= -9
Hope this helps!
Answer:
martina is 22 feet below sea level
Step-by-step explanation:
Marina goes down 20 feet
then rises 7 feet which is 20 - 7 = 13

20 - 7 + 9 =22
Martina is 22 feet below sea level.
