Here are a number of ways to add a vertical line
Plot[x^2, {x, -1, 1},
Epilog -> {Red, Line[{{0.5, -0.05}, {0.5, 1.05}}]}];
Plot[x^2, {x, -1, 1}, GridLines -> {{0.5}, None}];
Show[Block[
{$DisplayFunction = Identity},
{Plot[x^2, {x, -1, 1}],
ListPlot[{{0.5, -0.05}, {0.5, 1.05}},
PlotJoined -> True, PlotStyle -> Red]}]];
