Choose the correct statement about best-fit lines. a. a best-fit line is close to most of the data points. b. a best-fit line describes the exact coordinates of each point in the data set. c. a best-fit line always has a positive slope. d. a best-fit line must go through at least two of the data points.

a.  A best-fit line is close to most of the data points.

Step-by-step explanation:

Line of best fit is the straight line which represents the data in the best way. This straight line is said to be best if the distances between the data points and the straight line are minimum.

Thus Option (a) is correct.

Option (b) is incorrect as best-fit lines never describe the exact coordinates of the data set.

Option (c) is incorrect as best-fit lines can have positive as well as negative slope.

Option (d) can't be chosen as it is not necessary that line must go through any of the data points.

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.
