Answer / Jyotsana Gunjiyal
To plot a line between two points (x1, y1) and (x2, y2) in Delphi, you can use the Graphics unit. Here is an example of how to create and plot a line using TGraph:nn```delphinvarn g: TGraph; // Create a new TGraph objectnbeginn SetLength(g.Points, 2); // Allocate space for two pointsn g.Points[0].X := x1; g.Points[0].Y := y1;n g.Points[1].X := x2; g.Points[1].Y := y2;n Graphics.BeginDraw(Canvas); // Start drawing on the Canvasn g.Draw(Canvas); // Draw the TGraph object (line)n Graphics.EndDraw(); // Finish drawingnend;n```
