4. Agile Mind Exploration
A surveillance helicopter reports a grass fire to the central dispatcher. The dispatcher locates the fire on a grid map and determines that the fire is 8 miles due east and 11 miles due north from the central dispatch office.

5. Which distances do we know?
X goes from 2 to 8 (leg)
Y goes from 3 to 11 (leg)
Which do we want to find out?
We want distance from station to fire (hypotenuse) c 8 6

6. Method 1: Pythagorean Thm.
a = 6, b = 8, c = ???
= c2
= c2
100 = c2 c 8 6

7. Method 2: Distance Formula
“D” for distance
11 – 3 = 8
8 – 2 = 6

8. In your vocabulary… Distance Formula
2 points (x1, y1) and (x2, y2). Distance between them is:
No drawing
NOW TRY THE NEXT EXAMPLE ON YOUR OWN. USE THE DISTANCE FORMULA TO SOLVE IT!!!!!! REMEMBER YOUR ORDER OF OPERATIONS

9. One more example:
Point P has coordinates (1,3). Point Q has coordinates (25,10). How long is segment PQ?
Once you finish this, begin the next activity. Read the directions!!!
