Nine points are evenly spaced on a standard number line. They are labeled A thorugh I, left to right. The coordinates of points A and I are 1 and 10, respectively. What is the coordinate of point B?
Let's see
A B C D E F H I
1 10
The space beween each point is (10 - 1) / 7 = 9 / 7
So....the coordinates of B = ( 1 + 9 /7) = 16/7
