Labeling points in a plot

Questions

Hello!
How can I label specific points in a ListPlot? I’m trying to find what I need in the Help Center but am unsuccessful so far.
I have to plot a few points and label them ABCDE. Also, I want to draw two vectors and label them as well.
I’m new to Mathematica and still have some difficulties understanding how things work, especially the visualization part. Right now I’m studying algebra at the university and have to write a paper.

v = {1, 2, 5, 7, 4};
Show[
 ListPlot[v, PlotRange -> {{0, 6}, {0, 7}}],
 Graphics[Text["A", {1, 1}, {0, -1}]],
 Graphics[Text["B", {2, 2}, {0, -1}]],
 Graphics[Arrow[{{0, 0}, {2, 6}}]],
 Graphics[Text["V1", {1, 3}, {0, -2}]]
 ]

Study the help page for each of those functions used and be sure to click on Details and Options on each of those pages.

Thank you! This is exactly what I have been struggling with whole afternoon! I’ve found Arrow primitive earlier, but labeling things has been a challenge. I’ve tried PlotLabel, PlotLegend and other similar directives, but somehow I missed Text primitive. So thanks for that!
