I believe the answer is -5/3

Y+2x=-1 could become y=-2x-1 and then set that and x+4 equal to each other -2x-1=x+4 and add 2x to both sides to get -1=3x+4 and subtract by 4 on both sides to get -5=3x then divide by 3 and get -5/3=x

Point A is located at ​(4, 8)​ and point B is located at ​(14, 10)​ . What point partitions the directed line segment ​ AB⎯⎯⎯⎯⎯
andrew11 [14]

The 1:3 ratio means that the distance from A to the point is 1/4 of the distance from A to B.

The difference of y-coordinates is 10-8 = 2. 1/4 of that is 2·1/4 = 1/2, so the point of interest will have y-coordinate 8 + 1/2 = 8 1/2. This apparently corresponds to the first selection:

... (6 1/2, 8 1/2)
