Which pair of lines are perpendicular a) y=2x-1 and 2y=-x+3 b) y=3x+4 and 3y-x=5 c) y=-4x+2 and x+4y=6 d) y=-6x-3 and 6x-y=4

The answer is A. A perpendicular equation will have the opposite and reciprocal slope as the original equation.

Once converted to the slope-intercept form of y = mx+b, we find the two equations for A are y = 2x-1 and y = (-1/2)x + 3/2. The opposite reciprocal of the first equation's slope (m in the equation form given) is -1/2, which as you can see if the slope of the other equation.

Two lines are perpendicular if their slopes multiply to -1. That means we have to look at each individual answer and see if the slopes multiply to -1.

y = 2x - 1 has a slope of 2

2y = -x + 3

y = -1/2x + 3 This has a slope of -1/2.

2 * -1/2 = -1.

Since the slopes of these lines multiply to -1, the answer is A. Since we have our answer, we don't have to do anything else.

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.
