plug 1 in for x to get 7y=3(1)-7

7y=-4
y=-4/7

[tex] \bf 7y=3x-7~\hspace{5em}(\stackrel{x}{1},\stackrel{y}{\phantom{X}})~\hspace{5em} \stackrel{x = 1}{7y=3(1)-7} \\\\\\ 7y=-4\implies y=\cfrac{-4}{7} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \left(\stackrel{x}{1},\stackrel{y}{-\frac{4}{7}}\right)~\hfill [/tex]
