draw the graph of two lines x=3 and y= -1 and find the relationship between them.
 

Dear Student,

The graph of x = 3 and y = -1 be as follows:

$\mathrm{Since} \mathrm{both} \mathrm{line} \mathrm{meets} \mathrm{at} \mathrm{point} \left(3,-1\right). \mathrm{Thus} \mathbf{x}\mathbf{+}\mathbf{3}\mathbf{y}\mathbf{=}\mathbf{0}$
