This.add.line not starting at 0?

Phaser 3
1

I’d like to draw a line starting at 0, 0 (meaning at the top left corner of my canvas).
However, the line seems to have an x offset of about 35px. Why is that?

function create () {
    this.add.line(0, 0, 35, 1, 100, 1, 0xffffff) //
    this.add.line(0, 0, 0, 10, 100, 10, 0xff0000) // seems to start outside of the canvas
}

Use .setOrigin(0, 0). All shapes have default origin (0.5, 0.5).
