Question

The slope of the straight line$\frac{ x}{10 }$-$\frac{y }{4 }$ = 3 is

• A. $\frac{5}{2 }$
• B. $\frac{ -5}{ 2}$
• C. $\frac{ 2}{ 5}$
• D. $\frac{ -2}{ 5}$

Answer 1

Answer: (C)

$\frac{ 2}{ 5}$

Answer 2

We have, $\frac{x}{10}-\frac{y}{4}=3$ $\Rightarrow 2 x-5 y=60$ $\Rightarrow 5 y=2 x-60$ $\Rightarrow y=\frac{2}{5} x-12 \,.......(i)$ Compare E (i) with $y=m x+c$, we get $m=\frac{2}{5}$. Thus, slope of straight line $=\frac{2}{5}$.
