Use the distance formula to find the distance between the given points.
Here is the distance formula:
d = sqrt{(x1 - x2)^2 + (y2 - y1)^2}
If you do not know how to use the formula, write back.

Use the distance formula: d=sqrt%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29


d=sqrt%28%282-%28-4%29%29%5E2%2B%28-1-3%29%5E2%29

d=sqrt%28%286%29%5E2%2B%28-4%29%5E2%29

d=sqrt%2836%2B16%29

d=sqrt%2852%29=2%2Asqrt%2813%29

Roughly 7.211, and to the nearest tenth, 7.2

Do the other one exactly the same way.
