Answer:
(A) If you write the coordinates on a graph, you can find the distance between the drinking fountain and bench by applying the distance formula: (x2-x1)^2 + (y2-y1)^2. So this is how to solve it:
1. (0--4)^2+(2-2)^2
2. (0+0)^2+(2-2)^2
3. (4)^2+0
4. √16
5. 4

(B) This is a right triangle because if you plot the points on a graph, it creates the shape of a right triangle.
I hope this helps!! If not then let me know. Good luck!
