<h3>Answer: 22 units</h3>
=====================================================
Explanation:
You can use the distance formula
----------------
A shorter method is to subtract the y coordinates and apply absolute value
So either |-4-18| = |-22| = 22
Or, |18 - (-4)| = |18+4| = |22| = 22
This method only works because the x coordinates are the same. We can also use this method if the y coordinates were the same with the x coordinates being different.
