Answer 1

thats not one of the options i provided?

Answer 2

To find the coordinates of point \( X \) that partitions the directed segment \( \overline{AB} \) in the ratio \( 1:2 \), we can use the section formula.

Given the points:
- \( A(-3, -4) \)
- \( B(1, 2) \)

The section formula for point \( (x, y) \) that divides the line segment \( AB \) in the ratio \( m:n \) is given by:

\[
x = \frac{mx_2 + nx_1}{m+n}
\]
\[
y = \frac{my_2 + ny_1}{m+n}
\]

Here, \( m = 1 \), \( n = 2 \), \( A(x_1, y_1) = (-3, -4) \), and \( B(x_2, y_2) = (1, 2) \).

Substituting the values into the formulas:

For \( x \):
\[
x = \frac{1 \cdot 1 + 2 \cdot (-3)}{1 + 2} = \frac{1 - 6}{3} = \frac{-5}{3}
\]

For \( y \):
\[
y = \frac{1 \cdot 2 + 2 \cdot (-4)}{1 + 2} = \frac{2 - 8}{3} = \frac{-6}{3} = -2
\]

Thus, the coordinates of point \( X \) are:

\[
X\left(-\frac{5}{3}, -2\right)
\]

From the responses provided, the correct option matching these coordinates is:

**X(− StartFraction 7 over 3 EndFraction,−2)**.
