4. Linear Equations in Two Variables
easy
रैखिक समीकरण $x+2 y=8$ का वह हल ज्ञात कीजिए जो निम्नलिखित पर एक बिंदु निरूपित करता है
$(i)$ $x-$ अक्ष
$(ii)$ $y-$ अक्ष
Option A
Option B
Option C
Option D
Solution
We know that the point which lies on $x$ – axis has its ordinate $0 .$
Putting $y =0$ in the equation $x +2 y =8$, we get $x+2(0)=8 \Rightarrow x=8$
A point which lies on $y$ – axis has its abscissa $0 .$
Putting $x =0$ in the equation $x +2 y =8$, we get
$0+2 y=8 \Rightarrow y=4$
