use the 3-dimensional version of the distance formula
d = ( x 2 - x 1 ) 2 + ( y 2 - y 1 ) 2 + ( z 2 - z 1 ) 2
let ( x 1 , y 1 , z 1 ) = ( - 2 , 1 , 3 ) and ( x 2 , y 2 , z 2 ) = ( - 1 , 4 , - 2 )
substitute these values into the formula.
d = ( - 1 + 2 ) 2 + ( 4 - 1 ) 2 + ( - 2 - 3 ) 2
d = 1 2 + 3 2 + ( - 5 ) 2 = 1 + 9 + 25 = 35
