Find the distance between the points (1, 2) and (4, 6).
Correct: B
The distance between two points (x1, y1) and (x2, y2) is given by the formula √((x2-x1)^2 + (y2-y1)^2). Substituting the given points (1, 2) and (4, 6) into the formula gives us √((4-1)^2 + (6-2)^2) = √(3^2 + 4^2) = √(9 + 16) = √25 = 5.
