The slope of the line below is 3. Use the coordinates of the labeled point to find a point-slope equation of the line. A. y – 8 = –3(x – 6) B. y – 8 = 3(x – 6) C. y – 6 = –3(x – 8) D. y – 6 = 3(x – 8)

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
