B, because people do selective breeding to get something they want out of it. Which decreases genetic diversity, genetic diversity meaning there being less and less traits and characteristics and we wont something perfect not exactly something with traits that we dont like. However dont get me wrong, nothings perfect. But yeah.
Hey there! :D
Plug in the points to see if they work.
y=7x
(2,14) -> (x,y)
14=7*2
14=14
That works.
(0,0)
0=7*0
0=0
That works
(1,7)
7=7*1
7=7
That works.
The points that work are (2,14), (0,0), and (1,7)
I hope this helps!

Answer: x = -1 and y = 5
Step-by-step explanation:
7x + 3y = 8 ........................... equation 1
4x - y = - 9 ............................ equation 2
Solving the simultaneous linear equation by substitution method , make y the subject of the formula from equation 2 , we have
y = 4x + 9 ............................. equation 3
substitute y = 4x + 9 into equation 1 , we have;
7x + 3 ( 4x + 9 ) = 8
7x + 12x + 27 = 8
19x + 27 = 8
subtract 27 from both sides
19x = -19
divide through by 19
x = -1
substitute x = -1 into equation 3 , we have
y = 4 ( -1) + 9
y = -4 + 9
y = 5
Therefore :
x = -1 and y = 5
