Question

A circle is centered at Q(1,-5) and has a radius of 5. Where does the point Y(4,-1) lie?

Answer 1

On the circle

Explanation:

Answer 2

Point Y (4, -1) lies on the circle.

Explanation:

Distance = √[(x2-x1)² + (y2 - y1)²] = √[(4-1)² + (-1-(-5))²] = √[3² + 4²]= √25 = 5

Point Y (4, -1) lies on the circle, because the distance from the center to this point equals radius of the circle.
