Find the y value for point f such that df and ef form a 1: 3 ratio. (5 points) segment de is shown. d is at negative 3, negative 3. e is at 2, 4. 1.67 −1.33 0.75 −1.25

The correct option is 4.

Step-by-step explanation:

It is given that DF and EF form a 1:3 ratio. The coordinates of the end points of the segment DE are D(-3,-3) and E(2,4).

According to the section formula, if a point p divides a line in m:n, then the coordinates of p are

y value for point F is calculated as

The end points of the segment DE are D(-3,-3) and E(2,4).

The y- value for point F is -1.25. Therefore the correct option is 4.
