Note that the equation of the circle is
(x-h)² +(y-k)² =r²
where centre is (h,k)
the equation of the circle based on the information given
(x-3)² +(y-4)² =r²
and the point on the circle (3,-2)
substitute into the equation
(3-3)² +(-2-4)² =r²
r=6 or r=-6
since r is radius, we reject r=-6 since radius must be nonnegative.
the radius is 6
Step-by-step explanation:
find slope first
38-8/-14-(-20) = 5
y = 5x + b
find y intercept by sub in any set value show as long as they are belongs together
8 = 5(-20) + b
8 = -100 + b
108 = b
y = 5x + 108
