1. What point is midway between -7 and 5?

2. What point is midway between (-3, 1) and (5, 4)? (1, 2.5)

3. Pythagorean Theorem: a2 + b2 = c2 c 4 42 + 52 = c2 16 + 25 = c2 41 = c2 c = 41 5

4. Find the distance between (1, 1) and (4, 5) 32 + 42 = c2 9 + 16 = c2 25 = c2 c = 5 4 3

5. Find the distance between (-4, -3) and (1, 2) 52 + 52 = c2 25 + 25 = c2 50 = c2 c = 50 = 5 2 5 5

6. Pythagorean Theorem: a2 + b2 = c2 c2 = a2 + b2 c= a2 + b2

7. Find the distance between (-4, 3) and (1, -5) (-4 – 1)2 + (3 – -5)2 = c2 (-5)2 + (8)2 = c2 25 + 64 = c2 89 = c2 c = 89 5 8

8. Find the distance between (5, 3) and (-2, -4) (5 – -2)2 + (3 – -4)2 = c2 (7)2 + (7)2 = c2 49 + 49 = c2 98 = c2 c = 98 = 7 2 7 7
