To determine if an ordered pair is a solution to a system of linear equations in two variables, a. substitute the coordinates of the ordered pair into either equation to see if it produces a true statement b. substitute the coordinates of the ordered pair in both equations to see if it produces a true statement for each c. substitute the coordinates of the ordered pair in the first equation to see if it produces a true statement d. substitute the coordinates of the ordered pair in the second equation to see if it produces a true statement

B

Step-by-step explanation:

When an ordered pair is a solution to a system of equations in two variables, it must mean that when you plug in the ordered pair into both equations, it must come out true (this is literally the definition of a solution to a system of equation). Technically, A is also facts, but B is a "more inclusive" facts so that's your answer. Hope this helps! :)

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
