To find the coordinate 3/5 of the way from A to B, you can use the formula for the point P that divides the segment AB in the ratio m : n:
Here, m = 3, n = 2 because 3/5 of the way corresponds to a ratio of 3 : 2. We know Ax = 1 and Bx = 11.
After substituting the values we know into the Px equation, we find that:
Px = 7
A simpler way to think about this is to find the horizontal (x) distance between the points and then add 3/5 of this distance to the x-coordinate of the starting point. The horizontal distance between A and B is:
11 - 1 = 10
3/5 of 10 = 6, so add 6 to the x-coordinate of A to find the x-coordinate of the point that is 3/5 of the way between A and B:
1 + 6 = 7
Hope this was helpful.
