Realy need someone to explain thai to me

B) 2

Step-by-step explanation:

Slope is the change in y over the change in x so to start you need to find the change in y. To do this subtract each number on the y side from the number that comes before it.

[-3-(-1)=-2] [-1-1=-2] [1-3=-2] [3-5=-2]

Do the same with the numbers on the x side

[-2-(-1)=-1] [-1-0=-1] [0-1=-1] [1-2=-1]

Now put the change in y (-2) over the change in x (-1) and you have your slope.

-2/-1 simplified equals 2

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
