Find the solution of the linear equation $x+2 y=8$ which represents a point on

$(i)\, x$ - axis $(ii)$ $y$ -axis

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

$0+2 y=8 \Rightarrow y=4$
