h;ow to write a method and get mouse left click and pass it to the another method

private void panel1_MouseMove(object sender, MouseEventArgs e)
{


Pen pen1 = new System.Drawing.Pen(Color.Black, 3);
Pen pen2 = new System.Drawing.Pen(panel1.BackColor, 3);
Graphics g = panel1.CreateGraphics();
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
// Clear the graphics, creating a blank area to d
g.Clear(panel1.BackColor);
g.DrawLine(pen1, new Point(0,0), new Point(e.Location.X, e.Location.Y));
x_previous = e.Location.X;
y_previous = e.Location.Y;
}

instead of 0,0 i want to pass mouse left click coordinates
