Question

The point (-11,2) ____on the circle with radius 5 and center (-7,4)

Answer 1

Does not lie

Explanation:

The equation of the circle is

`{(x + 7)}^(2) + {(y - 4)}^(2) = 25`

If we substitute x=-11, and y=2, we get that:

`{( - 11 + 7)}^(2) + {(2 - 4)}^(2) = 25 \\ {4}^(2) + {2}^(2) = 25 \\ 20 = 25`

Which is false, meaning it does not lie on the circle
