I also noticed that Solve does not need the Thread. This also works:

Plot[Evaluate[y /. {
    Solve[{x, y} == {2 t, -t^2}, {y, t}],
    Solve[{x, y} == {6 + 2 t, -t^2}, {y, t}]}],
 {x, -4, 10},
 Axes -> {True, False},
 Ticks -> None,
 PlotStyle ->
  {{Thick, Cyan}, {Thick, Green}},
 PlotRange -> {-4, 0},
 AspectRatio -> 0.285714,
 Filling -> -4]
