Note the general equation of a circle is x^2 + y^2 = r^2, with centre (0, 0) and radius: r.
So, our equation of a circle is (x + 3)^2 + (y - 1)^2 = 100
Subtract 100 from both sides and plug in the points. If it equals to 0, then the points satisfy the equation of the circle (ie lies on the circle)
Answer: Quadrant 1 (northeast quadrant)
=================================================
Explanation:
Add on 360 degrees to do a full rotation
-302+360 = 58
So angles -302 degrees and 58 degrees are pointing in the same direction. These angles are in quadrant 1, which is the northeast quadrant
Note: because the angles -302 and 58 point in the same direction, we consider these angles to be coterminal.
