Find the coordinates of the point p that divides the directed line segment from a to b in the given ratio.
a(-1,7), b(23,-9); 7 to 1
the coordinates of point p are (

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
