Question 1133786
(1) {{{ x = 5 }}}
(2) {{{ 2x - 3 = 25 }}}
------------------------
The 1st equation is a vertical line since no
matter what y is, x is always 5
(2) {{{ 2x = 25 + 3 }}}
(2) {{{ 2x = 28 }}}
(2) {{{ x = 14 }}}
This is also a vertical line for the same reason,
so these lines are parallel
--------------------------------
You said the 1st equation only has a y-intercept.
In that case the equation would be {{{ y = 5 }}}
and then the lines would be perpendicular
