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 r between points (a,b) and (c,d) satisfies
[tex]r^2 = (a-c)^2 + (b - d)^2[/tex]
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:
[tex]r = \sqrt{(a-c)^2 +(b-d)^2}[/tex]
