Answer:
The current population (in 2005) is 4000 because it is the constant. The slope tells us how many people are added to the population, so 70 per year. For ex. 2008 (2008- 2005 = 3=> 3 x 70 = 210 => 210 + 4000 = 4210).
X=7. if you need explanation message me
slope = (6 - 1)/(-2 - 1) = 5/-3 = -5/3
Equation
y - 6 = -5/3 (x + 2)
Hope it helps
A perfect square is a number made by squaring a whole number.
Since
numbers 1, 16, 100 are perfect squares. You cannot find such whole number n, that
therefore, numbers 2, 18, 32, 44, 94 are not perfect squares.
Answer: 1, 16, 100.
I think you mean,

You can use the usual formula,

That in this case is,
