Answer:
The radius of the circle is 17 units. The point (-15,-16) or (-15,14) lies on this circle.
Step-by-step explanation:
It is given that the circle is centered at the point (-7, -1) and passes through the point (8, 7).
Distance formula:
Using distance formula we get,
The radius of the circle is 17 units.
Let the circle passing through the point (-15,y).
Taking square root both the sides.
Taking square root both the sides.
The value of y is either -16 or 14.
Therefore the radius of the circle is 17 units. The point (-15,-16) or (-15,14) lies on this circle.
