Final answer:
The distance between points B(3, 6) and C(3, 3) is the absolute difference of their y-coordinates, which is 3 units.
Step-by-step explanation:
The question asks to find the distance between points B(3, 6) and C(3, 3) on a coordinate plane. The distance between two points on a coordinate plane can be calculated using the distance formula, which is the square root of the sum of the squares of the differences between the x-coordinates and the y-coordinates of the points. However, since the x-coordinates of B and C are the same, the distance between them is simply the absolute difference of their y-coordinates.
Distance BC = |y2 - y1|
Distance BC = |6 - 3| = 3 units
Therefore, the correct answer to the question is A) 3 units.
