Answer:
Part 1) The radius of the circle is r=17 units
Part 2) The points (-15,14) and (-15,-16) lies on this circle
Step-by-step explanation:
step 1
Find the radius of the circle
we know that
The distance between the center of the circle and any point on the circle is equal to the radius of the circle
the formula to calculate the distance between two points is equal to
we have
(-7, -1) and (8, 7)
substitute
step 2
Find out the y-coordinate of point (-15,y)
The equation of the circle in standard form is equal to

where
(h,k) is the center
r is the radius
substitute the values


Substitute the value of x=-15 in the equation




square root both sides




therefore
we have two solutions
point (-15,14) and point (-15,-16)
