This one's a tricky one. Subtracting the respective coordinates is the first step. But that in itself doesn't give the distance; there's some squaring and adding and square rooting to do. I'm going to go with
Answer: false
Rather than worry about this confusing question, let's review the distance formula. I find it easier to think of as the Pythagorean theorem. The distance <em>r</em> between points (<em>a,b</em>) and (<em>c,d</em>) satisfies
When I'm doing math I usually try to avoid taking a square root. But if we're asked directly for the distance, it's often unavoidable:
