What is the distance between the points (-3, 1) and (2, 13)?
Answer and explanation
Correct answer: D. 13
- Step 1: Distance = root[(x2 - x1)^2 + (y2 - y1)^2] = root(25 + 144). Step 2. = root 169 = 13. Answer: 13. Why not the others: 17: That adds the horizontal and vertical differences instead of using Pythagoras. 169: That is the squared distance. 14: That is one more than the correct distance.
