Find the vector equation of each one of following plane: `x+y=3`

Explanation

`x+y=3` This is in Cartesian form, to convert this to vector form, this can be done as shown below:



`(x \hat{\i}+y \hat{\j}+z \hat{k}) \cdot(\hat{\i}+\hat{\j})=3`



We know `x \hat{\i}+y \hat{\j}+\rm{z} \hat{\rm{k}}= {\rm{r}}`
