The epicenter of an earthquake is the point on Earth's surface directly above the earthquake's origin. A seismograph can be used to determine the distance to the epicenter of an earthquake. Seismographs are needed in three different places to locate an earthquake's epicenter. Find the location of the earthquake's epicenter if it is 2 miles away from A(−2, 5), 4 miles away from B (2, 3), and 7 miles away from C (-2,-4).

Can I request that someone tell me how to solve this problem on a ti-84 graphing calculator? I know how to solve it on desmos, but what can I do without graphing this on anything other than a calculator?
