What is the distance between the points (1, 2) and (4, 6)?
Answer and explanation
Correct answer: D. 5
- Step 1: Distance = root[(x2 - x1)^2 + (y2 - y1)^2] = root(9 + 16). Step 2. = root 25 = 5. Answer: 5. Why not the others: 7: That adds the horizontal and vertical differences instead of using Pythagoras. 25: That is the squared distance. 6: That is one more than the correct distance.
