Answer:
the strand contains 28% of adenine.
Step-by-step explanation:
We have only four components, and we only know one of them:
![\left[\begin{array}{cc}C&?\\G&22\%\\A&?\\T&?\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7DC%26%3F%5C%5CG%2622%5C%25%5C%5CA%26%3F%5C%5CT%26%3F%5Cend%7Barray%7D%5Cright%5D)
Cytosine has a relation 1 to 1 with G, therefore the strand must contain the same amount of C as it posses G:
![\left[\begin{array}{cc}C&22\%\\G&22\%\\A&?\\T&?\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7DC%2622%5C%25%5C%5CG%2622%5C%25%5C%5CA%26%3F%5C%5CT%26%3F%5Cend%7Barray%7D%5Cright%5D)
Therefore:

This is because the strain only contains those 4 components.
since A and T have also a 1 to 1 relation, we can state that A = T in quantity.
So:





I think it’s red. Have a good day.
Step-by-step explanation:
By 2 point form
y-y1= m(x-x1)
y-2 = -3(x-1)
y-2=-3x+3
3x+y=5... this is the required line
