    The quickest way to do it is to find the length of the unit segment. Then multiply by the total number of unit segments that span segment MN.

    The unit segment. If you notice, the entire length of MN can be broken down into six equal segments. Of those six smaller segments, if you take one of them, it would represent the unit segment.

    Can you walk me through using numbers I learn better that way.

    We'll get to that. But first, do you see that there are six unit segments?

    Okay, now all we have to do is take just one of those segments create a right triangle and apply pythagorean theorem. Notice the length of the legs of the triangle is just one unit. The pythagorean theorem is a^2 + b^2 = c^2. If we let a and b represent the length of the legs, then \(1^2 + 1^2 = c^2\) or \(1 + 1 = c^2\) or simply \(2 = c^2\). So \(\sqrt{2} = c\)

    \(c\) is the length of one unit segment. Multiply that by 6 and you'll have the length of \(MN\)

    surely it is simpler to apply pythag to the entire interval

    In theory, yes, but if properly applied, this is the simpler method.

    \[{MN}^2 = (4-(-2))^2 + (8-2)^2\\ {MN} = \sqrt{(4-(-2))^2 + (8-2)^2}\]

    so you have a right angled triangle, with two sides equal to 6, and you want to find the hypotenuse pythag. says: 6^2 + 6^2 = MN^2

    ie MN = √ ( 6^2+6^2 )
