Question

If (−7, m) is on a circle with center c(3, 5) and radius 10, what is the value of m? m = 5 m equals negative five plus two square root of 21 end square root m = −5 m equals five plus two square root of 21 end square root

Answer 1

${(x - 3)}^{2} + {(y - 5)}^{2} = 100 \\ 100 + {(y - 5)}^{2} = 100 \\ y = 5$
