Line segment xy has endpoints x(–10, –1) and y(5, 15). to find the y-coordinate of the point that divides the directed line segment in a 5: 3 ratio, the formula y = (a/a+b) (y2 – y1) + y1 was used to find that y = (5/5+3) (15 – (–1)) + (–1).

therefore, the y-coordinate of the point that divides xy into a 5: 3 ratio is?

The y co-ordinate is 9

Step-by-step explanation:

We simplify the expression given by the formula;

The y-coordinate is 9.

Step-by-step explanation:

The given line segment has endpoints X(-10,-1) and Y(5,15).

The formula for finding the y-coordinate of the point that divides the directed line segment in the ratio a:b is

.

The given ratio is 5:3.

We plug in the values to get

We simplify to get;

.

c
