slope-point form:
we need the slope (m) and a point.
y-y₀=m(x-x₀)
Given two point A(x₁,y₂) and B(x₂,y₂), the slope of the line is :
m=(y₂-y₁) /(x₂-x₁)
Example 3:
we can take two points:
A(12,2)
B(13,7)
m=(7-2) / (13-12)=5/1=5
therefore:
y-2=5(x-12)
y-2=5x-60
y=5x-60+2
y=5x-58
answer: y=5x-58
Example 4:
we can take two points.
A(0,0)
B(3,1)
m=(1-0)/(3-0)=1/3
Therefore:
y-0=1/3(x-0)
y=x/3
answer: y=x/3
Expand the equation by multiplying it with itself: (x-3)*(x-3)
x^2 - 3x - 3x + 9 = 5
x^2 - 6x + 9 = 5
x^2 -6x +4 = 0
Since this is not part of the choices, try a different approach. Take the square root of both sides:
x - 3 = square root of 5
x - 3 = +/- 2.24
I guess this is the middle term which is incomplete. The first and last choices are not equivalent to the given equation.

This is an example of an exponential growth problem.
The formula for this is : y = x(1+r)^t
y = final amount
x = starting amount = 36
r = rate = 8% = 0.08
t = time = 11 days
y = 36(1+0.08)^11
y = 36 (1.08)^11
y = 36*2.3316389
y = 83.94 = 84 people
