Step-by-step explanation:
Given
f(t) = Population of females
g(t) = Population of people
Required
Determine the population of males
Represent the required population with h(t)
With the assumption that, one can either be male or female (but not both), the relationship between f(t), g(t) ang h(t) is:

i.e.

Make h(t) the subject in 

Answer:
A
Step-by-step explanation:
we can find out by writing its equation;
9-(-3) / (14-4) = 12 / 10 = 6 / 5
so its equation gonna be y = 6/5x - 7.8
.
now we can grid in the answer choices:
-9 = -6/5 -7.8 so (-1 , -9) is the correct answer
.
