Question

point p partitions the directed line segment from a to b into the ratio 3:4. will p be closer to a or b? why?

p will be closer to a because it will be \\(\frac{3}{7}\\) the distance from a to b.
p will be closer to a because it will be \\(\frac{4}{7}\\) the distance from a to b.
p will be closer to b because it will be \\(\frac{3}{7}\\) the distance from b to a.
p will be closer to b because it will be \\(\frac{4}{7}\\) the distance from b to a.

<reasoning>

Analyze the partition ratio

\[
\text{Ratio } AP : PB = 3 : 4
\]

Calculate fractional distance from A to B

\[
\frac{AP}{AB} = \frac{3}{3 + 4} = \frac{3}{7}
\]

Determine proximity to endpoints

\[
\frac{3}{7} < \frac{1}{2} \implies AP < PB \implies P \text{ is closer to } A
\]
