Answer:

[tex]\left(\displaystyle -\frac{2}{5},\frac{4}{5}\right)[/tex]

Step-by-step explanation:

Proportions

The coordinates of the point R are (-6,4) and the coordinates of the point S are (8,-4). We must find the coordinates of a point P(x,y) such that the ratio of segment RP to segment PS is 2/3. Let's find the coordinates separately. In the x-axis:

[tex]\displaystyle \frac{-6-x}{x-8}=\frac{2}{3}[/tex]

Operating and rearranging

[tex]-18-3x=2x-16[/tex]

Solving

[tex]\displaystyle x=-\frac{2}{5}[/tex]

Now for the y-axis

[tex]\displaystyle \frac{4-y}{y+4}=\frac{2}{3}[/tex]

Operating and rearranging

12-3y=2y+8

Solving

[tex]\displaystyle y=\frac{4}{5}[/tex]

Thus, the point that partitions the segment in the ratio 2 to 3 is

[tex]\left(\displaystyle -\frac{2}{5},\frac{4}{5}\right)[/tex]
