What is the distance between the points (–5, –9) and (–5, 13)?
Since they have the same x-value, -5, that means this is conveniently a vertical line.
So the distance is just the distance (number of units) from -9 to 13.
This is the number of units you count if you start at -9 and end at 13.
Or, you could just find -9 minus 13, but leave out the negative sign afterwards, b/c the number of units is positive.
