The standard deviation from the mean of a young (30-year old) adult is called a t-score.
If the t-score is -1, it means that the bone density is 1 standard deviation below the mean.
It is generally considered a t-score between -1 and -2.5 low bone density.
Patients with t-scores below -2.5 (e.g. -3) is considered suffering from osteoporosis.  Also, patients within this range AND suffered from one or more fractures is considered established osteoporosis.

Write the equation of a line perpendicular to y=3x+1and goes through the point ( 6,2) y=−13x+4 y=−13x−4 y=3x+4 y=3x−4
Korolek [52]

Answer:

y=-\frac{1}{3}x+4

Step-by-step explanation:

step 1

Find the slope of the perpendicular line

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal

(the product of their slopes is equal to -1)

In this problem

we have

y=3x+1

The equation of the given line is m=3

so

the slope of the perpendicular line to the given line is

m=-\frac{1}{3}

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=-\frac{1}{3}

(x1,y1)=(6,2)

substitute

y-2=-\frac{1}{3}(x-6)

Convert to slope intercept form

y=mx+b

Distribute right side

y-2=-\frac{1}{3}x+2

y=-\frac{1}{3}x+2+2

y=-\frac{1}{3}x+4
