Answer:

x^2+y^2=13

Step-by-step explanation:

radius is the distance from the origin to the point

r=(2^2+3^2)^(1/2)=13^(1/2)

x^2+y^2=(13^(1/2))^2=13

First we need to find the gradient of K
which is y1-y2/x1-x2
(-1,3) and (5,-2)
so it becomes 3-(-2)/-1-5
m=-5/6
when two lines are perpendicular their gradients multiply to make -1
that means the gradient of L has to be 6/5
we can substitute the point on L (5,-2) and the gradient of 6/5 into y=mx+c
-2 = (6/5) x 5 + c
c = -8
the equation of line L is y= 6x/5 -8
