Question

Find the distance between two points A(-3, 2) and B(-3, -3).

• A. 4 units and parallel to X-Axis
• B. 5 units and parallel to Y-Axis
• C. 4 units and parallel to X-axis
• D. 5 units and perpendicular to X-axis

Answer 1

Answer: (B), (D)

5 units and perpendicular to X-axis


Here the X-coordinate of both points is the same.
Therefore, the line segment AB will be parallel to Y-Axis.
Hence the distance between two points,
$AB=|Y_2-Y_1|$
$\Rightarrow AB=|-3-2|$
$\Rightarrow AB=|-5|$
$\Rightarrow AB=5units$
