What's the Midpoint of Two Points on a Number Line?

What is the midpoint of two points on a number line?

Summary

  1. M is the value of the midpoint
  2. x1 and x2 are the two points on the number line
  3. Using the formula, we find that the midpoint between -4 and 8 is 2
  4. Start out at each of the two points and move inward one unit at a time
  5. The point you get to at the end is the midpoint
  6. Just like before, this point is 2

Notes

    1. Here we are really just finding the average value of the two points
    2. That's all the midpoint is!
    1. -4 and 8 are our two points, and we want to find their midpoint
    1. Once we label the numbers, we can plug them into our formula to find their midpoint
    1. M stands for the midpoint
    2. Remember, we called -4 x1
    3. And we called 8 x2
    4. Adding two numbers together and dividing them by 2 is the same as finding their average
