To find out how to specify styles for GridLines, Plot with default GridLines.
plt = Plot[x^2+3x-4, {x,-5,5},
Frame->True, Axes->False,
PlotStyle->Blue,
GridLines->Automatic];
Use AbsoluteOptions to see the GridLines specifications
First /@ (GridLines /. AbsoluteOptions[plt])
{{-4., {RGBColor[0., 0., 0.5], AbsoluteThickness[0.25]}},
{-5., {RGBColor[0., 0., 0.5], AbsoluteThickness[0.25]}}}
Follow the template
Plot[x^2+3x-4, {x,-5,5},
Frame->True, Axes->False,
PlotStyle->Blue,
GridLines->{
Table[{x,{GrayLevel[.7]}},{x,-4,4,2}],
Table[{y,{Red}},{y,-5,15,5}]}];
