SOLUTION: I am trying to figure the distance using d = sqrt (x^2 - x^1)^2 + (y^2 - y^1)^2 for (-4,0) and (-5,-3); I am getting confused with the negatives. Is this the right formula?

Find the distance between (-4, 0) and (-5, -3)
The formua is:
d+=+sqrt%28%28x2-x1%29%5E2+%2B+%28y2-y1%29%5E2%29 Substitute: (-4, 0) for (x1, y1) and (-5, -3) for (x2, y2)
d+=+sqrt%28%28-5-%28-4%29%29%5E2+%2B+%28-3-0%29%5E2%29 Simplify.
d+=+sqrt%28%28-1%29%5E2+%2B+%28-3%29%5E2%29
d+=+sqrt%281%2B9%29
d+=+sqrt%2810%29
