Multiple Choice

What is the formula to find the distance d between two points $\left( x _ { 1 } , y _ { 1 } \right)$ and $\left( x _ { 2 } , y _ { 2 } \right)$ ?

• A) \(d = \sqrt { \left( x _ { 2 } + x _ { 1 } \right) ^ { 2 } + \left( y _ { 2 } + y _ { 1 } \right) ^ { 2 } }\)
• B) \(d = \sqrt { \left( x _ { 2 } + x _ { 1 } \right) ^ { 2 } - \left( y _ { 2 } + y _ { 1 } \right) ^ { 2 } }\)
• C) \(d = \sqrt { \left( x _ { 2 } - x _ { 1 } \right) ^ { 2 } + \left( y _ { 2 } - y _ { 1 } \right) ^ { 2 } }\)
• D) \(d = \left( x _ { 2 } - x _ { 1 } \right) ^ { 2 } + \left( y _ { 2 } - y _ { 1 } \right) ^ { 2 }\)
• E) \(d = \sqrt { \left( x _ { 2 } - x _ { 1 } \right) ^ { 2 } - \left( y _ { 2 } - y _ { 1 } \right) ^ { 2 } }\)
