3. The coordinates of the points A and B are (1, 5)
and (2, -3) respectively. Find the equation of
the line passing through the origin and having
the same gradient as AB.

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
