Question

Find the midpoint of a line segment with endpoints at (0, 1) and (5, 7)?

  1. (1, 1)    
  2. open parentheses fraction numerator 5 over denominator 2 end fraction comma 4 close parentheses    
  3. open parentheses fraction numerator 5 over denominator 2 end fraction comma fraction numerator 5 over denominator 2 end fraction close parentheses    
  4. open parentheses fraction numerator 5 over denominator 2 end fraction comma fraction numerator 9 over denominator 2 end fraction close parentheses    

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: open parentheses fraction numerator 5 over denominator 2 end fraction comma 4 close parentheses


    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:
    open parentheses fraction numerator x subscript 2 end subscript plus x subscript 1 end subscript over denominator 2 end fraction comma fraction numerator y subscript 2 end subscript plus y subscript 1 end subscript over denominator 2 end fraction close parentheses
    Plug in the (x, y) values from the given points and solve.
    open parentheses fraction numerator 5 plus 0 over denominator 2 end fraction comma fraction numerator 7 plus 1 over denominator 2 end fraction close parentheses
    open parentheses fraction numerator 5 over denominator 2 end fraction comma fraction numerator 8 over denominator 2 end fraction close parentheses
    We can simplify the fraction to get the final answer.
    open parentheses fraction numerator 5 over denominator 2 end fraction comma 4 close parentheses
    Therefore, the midpoint of a line segment with endpoints at (0, 1) and (5, 7) is open parentheses fraction numerator 5 over denominator 2 end fraction comma 4 close parentheses.
