Line segment

For the line segment whose endpoints are L[-1, 13] and M[18, 2], find the x and y value for the point located 4 over 7 the distance from L to M.

Correct result:

x =  9.86
y =  6.71

Solution:

$x=-1+4\mathrm{/}7\cdot (18+1)=9.86$

$$\begin{gathered} y=13+4\mathrm{/}7\cdot (2-13)=6.71 \\ A[9.86,6.71] \end{gathered}$$
