Question

write a linear equation in two variables such that each on its graph has its ordinate equal to twice it's abscissa.

Answer 1

Dear student

$$\begin{gathered} \mathrm{Here}\mathrm{ordinate}=2\times \mathrm{abscissa} \\ \Rightarrow \mathrm{y}=2\mathrm{x} \\ \mathrm{So}\mathrm{required}\mathrm{eq}\mathrm{is}2\mathrm{x}-\mathrm{y}=0 \\ \mathrm{Solutions} \\ 1)\mathrm{when}\mathrm{x}=1 \\ \mathrm{y}=2 \\ 2)\mathrm{when}\mathrm{x}=0 \\ \mathrm{y}=0 \\ 3)\mathrm{when}\mathrm{x}=-1 \\ \mathrm{y}=-2 \end{gathered}$$

x	1	0	-1
y	2	0	-2
