s = 20
49=-7k is equivalent to D because when you simplify both of them, you get -7=k
Answer:

y=9
Step-by-step explanation:
Slope: 9-9/-2-15=0
Therefore, y=0x+b
Plug values in: 9=0(-2)+b
0+b=9
b=9
Therefore, equation is y=9
Mathematically, yes.
Realistically, no.
The difference in their ages is the parent's age when the child was born.

Then the ratio would be 10:9 when the parent is 120 and the child is 108.
Not likely.
