Step-by-step explanation:
Given


Required
Determine the total number of markers
First, we need to determine the ratio of black to blue such that


Multiply the ratio by 5


By direct comparison:


The above shows that:

So:



The given term is:
Since here, the numerator i.e.

cannot be factorized.
SO, the only excluded value is found on the basis of the denominator. The denominator should not be equal to 0, otherwise, the fraction will turn out to be zero.
SO, if y

-4, then denominator will not be zero.
Therefore, the excluded value is -4
The line passes through (2,-3) and (4,2).
Calculate the slope of the line.
m = (2+3)/(4-2) = 5/2
The equation of the line is therefore

Cross multiply.
2(y-2) = 5(x-4)
2y - 4 = 5x - 20
2y = 5x - 16
Rewrite as
5x - 2y = 16
Answer: C. 5x - 2y = 16
