When you have two things you'd like to line up with one another you can use the Align tool. It's hiding on the Home ribbon tab > Modify > (Expand the drop down "arrow) > Align button (left side bottom row).
You can let it scale the selected objects too. It's an option you'll find at the command line, Yes or No, before you finish the command.
If memory serves there wasn't always a button on the User Interface for Align. It was a secret command, like a secret handshake. If you know that AutoCAD has an Align tool then you really know AutoCAD. Just like the Cycle feature...(sshh, it's a test...do you know AutoCAD). Have to admit it is a pretty exasperating feature though.
