Question: 281
11.
The distance between points A and B in the coordinate plane above is
- A. 5
- B. 6
- C. 8
- D. 10
Correct Answer: D
Explanation:
D To find the distance between two points, draw a right triangle and use the Pythagorean Theorem. Draw a line straight down from point B and directly right from point A. That point will be (7,1), which you can label C. The distance from A to C is 6, and the distance from C to B is 8. Use the Pythagorean Theorem to find the missing side: 62 + 82 = c2. Simplify the left side to get 36 + 64 = 100. Take the square root of both sides to get c = 10. The correct answer is (D).
