Answer:

  • A. (-2, 4)

Step-by-step explanation:

Given the circle:

  • [tex]x^2+y^2=25[/tex]

or

  • [tex]x^2+y^2=5^2[/tex]

According to the equation, any point with one of the coordinate > 5 lies outside of the circle since the radius is 5 units.

The points 2, 3 and 4 have at least one of the coordinates greater than 5.

Let's verify the point 1:

  • [tex](-3)^2+4^2=9+16=25\\[/tex]
  • [tex]25=25[/tex]
