Question 517026: 10th Grade Geometry heres the question:
given points A(-4,-9) and B(7,-6) find AB, the length of line segment AB.
What formula (if needed) do I use to find the answer?
*note: I tried using (X1+X2),(Y1+Y2) divided by two, but then I only ended up with one point.
My teacher gave us the answer in class it's 11.4 and 12.52 I just dont know how to get there.
