*Flesch Kincaid readability measures are all over the board. Results are similar to those found via the Fry graph. This supports my premise that it is difficult to measure readability of math books. Nonetheless, they are difficult for most students to read.*

**Your text:** The Distance Formula

We now find a formula for the distance d(A,B) because two points A(x1,y1) and B(x2,y2) in the plane. Recall from Section P2 that the distance between points a and b on a number line is d(a,b)=|b-a|. So from Figure 4 we see that the distance between the points A(x1,y1) and C(x2,y1) on a horizontal line must be |x2-x1|, and the distance between B(x2,y2) and C(x2,y1) on a vertical line must be |y2-y1|.
