How do I get a GameObject to move left and up at the same time?

I have only been on Unity for 3 or 4 days, so feel free to talk to me like I had my brain removed.

// Both options are equal
transform.Translate((Vector3.left + Vector3.up)); // Option 1: more readable
transform.Translate(new Vector3(-1, 1, 0)); // Option 2: magic mumbo jumbo

Of course, the example is not optimal, because you need deltaTime and speed.

transform.Translate((Vector3.left + Vector3.up) * Time.deltaTime * 0.1f); // To slow down
