Choose the system of equations which matches the following graph: Question 11 options:

1)

x − 2y = 8

2x + 4y = 12

2)

x − 2y = 8

2x − 4y = 12

3)

x + 2y = 8

2x + 4y = 12

4)

x + 2y = 8

2x − 4y = 12

Thanks for helping me!

Icould really use some with this question.

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).
