For example I want to plot the vector <7, 20> on the same plot as the line {t, 6t+10}

Plot[
 Tooltip[6 t + 10], {t, 0, 8},
 Epilog -> {Red,
   Tooltip[
    Arrow[{{0, 0}, {7, 20}}],
    "Vector <7, 20>"]},
 AxesOrigin -> {0, 0},
 AxesLabel -> (Style[#, 14, Bold] & /@
    {"t", "y[t]"})]

enter image description here

EDIT: For a parametric curve rather than a line use ParametricPlot

ParametricPlot[
 Tooltip[{t + 5 t^2, 6 t + 10}], {t, 0, 3/2}, 
 Epilog -> {Red, Tooltip[Arrow[{{0, 0}, {7, 20}}], "Vector <7, 20>"]},
  AxesOrigin -> {0, 0}, 
 AxesLabel -> (Style[#, 14, Bold] & /@
    {"x[t]", "y[t]"}),
 AspectRatio -> 1/GoldenRatio]

enter image description here
