easy

उन बिंदुओं के निर्देशांक ज्ञात कीजिए जहाँ समीकरण $3 x+4 y=12$ का आलेख $x-$ अक्ष और $y-$ अक्ष को काटता है।

Option A
Option B
Option C
Option D

Solution

The graph of the linear equation $3 x+4 y=12$ cuts the $x$ -axis at the point where $y=0 .$ On putting $y=0$ in the linear equation, we have $3 x=12,$ which gives $x=4 .$ Thus, the required point is $(4,0).$

The graph of the linear equation $3 x+4 y=12$ cuts the $y$ -axis at the point where $x=0$. On putting $x=0$ in the given equation, we have $4 y=12,$ which gives $y=3 .$ Thus, the required point is $(0,3).$
