A particle moves along the straight line $y=3 x+5$. Which coordinate changes at a faster rate?

A

$x$-coordinate

B

$y-$coordinate

C

Both $x$ and $y$ coordinates

D

Data insufficient.

Solution

(b)

$y=3 x+5 \Rightarrow \quad \frac{d y}{d t}=3 \frac{d x}{d t}$

$\Rightarrow y$-coordinate changes at faster rate.
