- \(9x-14y+3=0\)
- \(11x+33y-16=0\)
- \(11x-33y-14=0\)
- \(x-3y-2=0\)

The Correct Option is C
Solution and Explanation
Let point \(P\) divide \(AB\) in ratio \(4:7\).
Using section formula:
\[
P=\left(\frac{4(5)+7(0)}{11},\frac{4(-3)+7(2)}{11}\right)
\]
\[
P=\left(\frac{20}{11},\frac{2}{11}\right)
\]
Slope given:
\[
m=\frac13
\]
Use point-slope form:
\[
y-\frac{2}{11}=\frac13\left(x-\frac{20}{11}\right)
\]
Multiply by \(33\):
\[
33y-6=11x-20
\]
Rearrange:
\[
11x-33y-14=0
\]
Thus,
\[
\boxed{11x-33y-14=0}
\]
