Question

Find the midpoint of the line segment which connects (− 6, 8) and (2, 12) ?

  1. (− 8, − 4)    
  2. (8, 4)    
  3. (− 2, 10)    
  4. (2, 10)    

hintHint:

The formula to find midpoint of line segment bounded by two points left parenthesis x subscript 1 comma y subscript 1 right parenthesis and left parenthesis x subscript 2 comma y subscript 2 right parenthesis is  open parentheses fraction numerator x subscript 1 end subscript plus x subscript 2 end subscript over denominator 2 end fraction comma fraction numerator y subscript 1 end subscript plus y subscript 2 end subscript over denominator 2 end fraction close parentheses

The correct answer is: (− 2, 10)


    The midpoint of a line segment is halfway between the two x values and halfway between the two y values. Mathematically, that would be the average of each coordinate.

    The midpoint of the line segment which connects (− 6, 8) and (2, 12)

    left parenthesis fraction numerator negative 6 space plus space 2 over denominator 2 end fraction space comma fraction numerator 8 space plus space 12 space over denominator 2 end fraction space right parenthesis space
left parenthesis fraction numerator negative 4 over denominator 2 end fraction space comma 20 over 2 right parenthesis
left parenthesis negative 2 space comma space 10 right parenthesis
    Therefore, our midpoint is (− 2, 10).
