Use the PlotStyle option

Needs["Graphics`Colors`"];

Plot[{Sin[x], Cos[x]}, {x,-3Pi/2,2Pi},
 
    PlotStyle -> {Red,
 
        {AbsoluteDashing[{5,5}],Blue}},
    Epilog->{
        Text["Sin", {Pi, .5}],
        Text["Cos", {Pi/2, -.5}]},
    ImageSize->350];

Needs["Graphics`Legend`"];

Plot[{Sin[x], Cos[x]}, {x,-3Pi/2,2Pi},
 
    PlotStyle -> {Red,
 
        {AbsoluteDashing[{5,5}],Blue}},
 
    PlotLegend->{"Sin[x]", "Cos[x]"},
 
    ImageSize->350];
